Solar Panels In New Jersey

In most cases, your solar panels will get a good cleaning every time it rains. However, if you’re in an area that doesn’t get rain very often, you can use a garden hose, a large sponge, and mild dish soap to clean your solar panels. Never use harsh chemicals, pressure washers, or any abrasives that might scratch the surface of your panels. Many solar panel installation companies will also offer inexpensive panel cleaning and maintenance.

In order to figure out how many solar panels you need, you’ll need to determine how much energy your household uses, how many panels you can fit on your roof, the peak sunlight in your area, how efficient the panels you’re considering are, and whether net metering is available in your area. The easiest way to find out is to get a solar panel estimate from a local installer.

Typically, an average-sized house will need 20 to 25 solar panels. However, depending on the size of the house, the sun exposure, where you live, and how much energy you consume, you could need more.

The time it takes to break even on your solar panel investment will depend on a number of things including the total cost for your system, whether you’re financing or you buy outright, and several other factors. However, the typical time range to break even is about 8 to 11 years for most residential solar panel systems.

Solar panels have a typical lifespan of 25 to 30 years. Once solar panels reach this point they begin to decline in efficiency. However, with recent advances in solar panel technology, it could make more sense to replace your solar panels in 10 years to maximize the improved efficiency.

The average solar panel weighs about 40 pounds. This will add about 2.8 pounds per square foot to pitched roofs, and about 5 pounds per square foot for flat roofs.
