What are Deep Cycle Batteries?

Deep cycle batteries are a type of rechargeable battery that are designed to be discharged and recharged multiple times. They are commonly used in a variety of applications, including solar power systems, wind power systems, and electric vehicles.

Deep cycle batteries are different from starting batteries (also called SLI batteries), which are designed to deliver a high current for a short period of time, like starting an engine. Deep cycle batteries, on the other hand, are designed to deliver a lower current over a longer period of time, making them ideal for applications where the battery is regularly discharged and recharged.

The most common types of deep cycle batteries are lead-acid batteries, which are widely used in a variety of applications. They are relatively inexpensive, durable, and easy to maintain, however they have a lower energy density compared to other types of batteries, and they are not as efficient in high-temperature environments. Another type of deep cycle batteries are Lithium-ion batteries, which have a higher energy density and they are more efficient in high-temperature environments, but they are more expensive and have a shorter lifespan than lead-acid batteries.

When it comes to deep cycle batteries, it’s important to choose the right type of battery for your specific application. Factors to consider include the depth of discharge (the amount of the battery’s capacity that will be used before recharging), the number of cycles the battery is expected to undergo, and the environment in which the battery will be used.

It’s also important to properly maintain deep cycle batteries, by keeping them clean, fully charged and at the right temperature. This will ensure that they last as long as possible and perform at their best.

In conclusion, deep cycle batteries are a type of rechargeable battery that are designed to be discharged and recharged multiple times. They are commonly used in solar power systems, wind power systems, and electric vehicles. The most common types of deep cycle batteries are lead-acid batteries and lithium-ion batteries. It’s important to choose the right type of battery for your specific application and properly maintain the batteries to ensure they last as long as possible.

What’s “Off-Grid Living”?

Off-grid living refers to the practice of living independently from the traditional power grid by generating one’s own electricity, water, and other necessities. This can be achieved through a variety of methods, such as solar power, wind power, hydropower, and even alternative energy solutions like biomass or geothermal.

One of the main benefits of off-grid living is the ability to be self-sufficient and not rely on the power grid or other public utilities. This can be especially appealing for those who live in remote or rural areas where access to the power grid is limited. Additionally, off-grid living can also be a more sustainable and environmentally-friendly lifestyle choice, as it reduces the dependence on fossil fuels and reduces the carbon footprint.

However, off-grid living also has its challenges. It can be costly to set up and maintain an off-grid system, and it requires a significant level of knowledge and expertise to install and maintain the system. Additionally, off-grid living often means living with limited resources and without the luxury of modern conveniences such as air conditioning, dishwashers, or other high-energy-consuming appliances.

In order to successfully live off-grid, it’s important to carefully plan and design the system. It’s also important to be aware of local regulations, as there may be legal restrictions or permit requirements for installing off-grid systems.

In conclusion, off-grid living is the practice of living independently from the traditional power grid by generating one’s own electricity, water, and other necessities. This can be achieved through a variety of methods such as solar power, wind power, hydropower, and alternative energy solutions. Living off-grid offers the benefits of self-sufficiency and sustainability but also comes with its own set of challenges like cost, maintenance, and limited resources. It is important to plan and design the system accordingly and be aware of local regulations.

Nova Scotia Power ‘working to resolve’ backlog of solar installation permits

The frontlines of solar energy say Nova Scotia Power is pushing their industry to a breaking point because of a backlog in permit approvals for hundreds of installations. The utility says it’s working diligently to get through the delay and is committed to green energy but opposition parties say that’s not the message they’re sending.

Nova Scotia’s solar energy sector went public this week with concerns over Nova Scotia Power’s processing time for solar installation permits.

“Huge demand for solar among Nova Scotians but we risk losing the summer install season with close to 1000 projects stalled,” Solar Nova Scotia tweeted on May 18, 2022.

For their part, the public utility says it is dealing with a backlog but it’s committed to working through it.

“Since January, we have processed approx. 650 electrical permitting requests and acknowledge that there continues to be a backlog which we are working to resolve as quickly as possible,” Stacy O’Rourke, Nova Scotia Power’s communications director, wrote in an email statement.

O’Rourke wrote that the utility is committed to phasing out coal and that processing permits for solar installations is a priority.

“Nova Scotia is not incentivized to bring on renewables at all, let alone in a timely fashion, and that’s a big problem,” said Claudia Chender, the Nova Scotia NDP critic for natural resources and renewables.

Chender says Nova Scotia Power’s attempt to charge solar customers a connection fee earlier this year demonstrates the need for the provincial government to reform how the utility is regulated.

“So that there’s a service standard for solar installation. So, that they’re incentivized differently not just for selling power but also for meeting our environmental targets and getting us towards renewables,” she said.

Tory Rushton, Nova Scotia’s minister of natural resources and renewables, says regulation changes are a possibility.

“I’ve been very clear right from day one, there’s nothing off the table. We made some amendments to the acts during the recent legislative sitting. We’re in the middle of regulations. This is an open file,” he said.

Rushton says the high demand from homeowners to have solar panels installed is a positive sign in Nova Scotia’s pathway to phasing out coal.

“I understand from comments made on social media from Solar Nova Scotia that there’s a high-interest rate so that’s a good thing. And we encourage Nova Scotia Power to move these things forward,” he said.

Solar For Boats & RV’s

Solar power is an increasingly popular choice for powering boats and RVs, as it is a clean, renewable, and cost-effective alternative to traditional fossil fuels.

Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electricity that can be used to power appliances, lights, and other electrical devices on a boat or RV. The size and power of the solar panels will depend on the specific needs of the boat or RV, as well as the amount of sunlight the panels will receive.

One of the key benefits of using solar power on a boat or RV is the ability to be off-grid. This means that a boat or RV can be parked in a remote location and still have access to power, without the need to rely on a generator or shore power. Additionally, solar power is silent and produces no emissions, which makes it a great choice for boating and RVing in sensitive or protected areas.

Solar power systems for boats and RVs typically include the solar panels, a charge controller, and a battery bank. The charge controller is responsible for ensuring that the batteries are not overcharged or undercharged, while the battery bank stores the electricity generated by the solar panels.

When it comes to solar power for boats and RVs, there are different options for the solar panel, such as flexible or semi-flexible solar panels, which are easy to install and can be attached to curved surfaces such as the deck or cabin of a boat, or traditional rigid solar panels which are more powerful but not as adaptable.

In conclusion, solar power is a clean, renewable, and cost-effective alternative to traditional fossil fuels for powering boats and RVs. It allows boaters and RVers to be off-grid, and it doesn’t produce emissions or noise. Solar power systems for boats and RVs include solar panels, charge controller, and a battery bank. There are different options for the solar panel such as flexible or traditional rigid solar panels.

The Advantages & Disadvantages of Grid Connected (Grid-tie) Systems

Photovoltaic cells are the main ingredient of all photovoltaic solar energy systems, turning sunlight directly into electricity. Since the first silicon photovoltaic cells were discovered in the 1950s, technological developments have improved performance and transformed solar energy capabilities. An increasingly viable and popular renewable energy source, grid-connected photovoltaic systems grabbed a 75 percent share of U.S. installations in 2009, up from 31 percent in 2001.

Grid Connected Basic Facts

General household electrical systems and appliances need alternating current power.

Being grid-connected means that a solar photovoltaic system is linked directly to the available electrical grid or utility lines. A connected system comprises a photovoltaic panel or set of panels that directly convert sunlight into electricity. The size of the system dictates how independent from the grid it’s possible to be. Grid-connected systems need inverters to convert direct current into alternating current usable electricity. The inverter connects to the main electrical supply with a meter showing the number of generated kilowatt hours. Excess electricity can be sold back to the grid.

Constant Reliable Power

Grid-connected photovoltaic systems guarantee a home always has access to power, even if the solar energy fails or is insufficient. The system’s inverter connects to a battery bank that can store energy to be used in a power failure. An advantage of grid-connected systems is that they are not dependent on the sun shining. Off-grid photovoltaic energy is only intermittent but grid-connected systems ensure that any additional electricity needed is automatically delivered by the grid.

Financial Benefits Of Grid Connected Systems

More than 35 states now have “net metering” legislation, meaning that householders benefit from selling excess energy back to the grid at normal retail prices. The Department of Energy notes that this puts people in Hawaii and New York at a great advantage because of the high retail electric rates. State and federal incentives include sales tax exemptions on the systems themselves, property tax exemptions, and personal state income tax credits.

As well to lower energy bills, grid-connected solar systems can add overall value to properties too. A federal study of California homes revealed that a 3,100-kilowatt hour system increases the home’s value by an average of $17,000.

Disadvantages Of Being Grid Connected

Installing solar systems near existing utility power lines means that photovoltaic generated electricity costs more than that supplied by conventional methods. At its cheapest, solar energy is estimated to be 25 cents per kilowatt hour — generally between double and quadruple the cost of utility-supplied electricity. Initial costs are high so in practice installing a grid-connected solar system is like paying your electricity bill up front, years in advance.

The permits and legal requirements for installing grid-connected systems can be costly, complex, and time-consuming. While national standards are beginning to be adopted, many regional agencies have different legislative procedures so the best starting point is the local city or county building department.

What Are the Best Solar Panels for Low Light?

The standard formula for rating solar panels looks at the amount of power the unit produces in full sunlight at 77 degrees Fahrenheit. However, many homeowners in northern latitudes might only reach that optimal standard for solar collection a few days per year. Suppose you live in an area where sunlight is weakened by such factors as inclement weather and the earth’s tilt, yet wish to take as full advantage of solar power as possible. In that case, you need solar panels that are optimized for better efficiency under substandard conditions.

Monocrystalline Panels

Of the three basic solar panel types–monocrystalline, polycrystalline and amorphous–monocrystalline is the most efficient in collecting solar energy and therefore somewhat more effective in regions with low sunlight. As the name suggests, they are made from a single large silicon crystal cut from an ingot. Polycrystalline panels use many small crystals to form the collection surface, while amorphous, or thin film, solar panels consist of silicon particles applied to the surface of large plates. Monocrystalline panels, while more efficient, are only slightly so. They are also the most expensive of the three types.

Hybrid Panels

Some manufacturers, including industry leader Sanyo technologies, have combined monocrystalline and amorphous thin film to produce a hybrid panel that Sanyo has dubbed Heterojunction with an Intrinsic Thin Layer (HIT). According to Sanyo’s marketing literature, these hybrid panels “boast high conversion efficiency ranging from 15.3 to 16.4, excellent temperature characteristics, and considerable output under diffuse and low light conditions.” Sanyo’s 190-watt photovoltaic (PV) module has earned a 17.4 percent efficiency rating, well above the industry average of 12 percent.

High-Powered Panels

Industry experts consider solar panels with a collection capacity of greater than 100 watts to be high-powered. The wattage of a panel describes the amount of power the panel can produce in full sunlight at 77 F. The selection of high-powered panels compatible with the typical household 12-volt system dwindles as the wattage soars upward because the highest powered panels are designed for grid-tie systems rather than stand-alone systems, which deposit the power in a battery storage bank. You must also keep in mind that two panels with lower wattage will add up to the same collection capacity and be less expensive. In the case of solar panels, bigger does not automatically equate to better.

More Options

The U.S. Department of Energy’s Efficiency & Renewable Energy Program (EERE), established to develop innovations in the solar panel field, is working to optimize solar collector efficiency. One example is an experiment using a MicroDish composed of a concentration of Spectrolab solar cells–ultra-high-efficiency cells–in which EERE tested the use of mirrors designed to multiply the sun’s power. This application is intended “to substantially increase the viability of PV for cost-competitive applications.”
