What Are Solar Panels? A solar panel, or photovoltaic (PV) panel, converts the sun’s energy into electricity. They’re most commonly composed of glass, wires and silicon and mounted on your rooftop or on the ground. Solar installations require a large number of panels to properly power your home. The configuration of solar panels, known as […]
Although Washington State’s cold and rainy weather may suggest otherwise, solar power has grown over the past decade. An increasing number of Washington residents are switching to solar, and more are looking for reliable installers in the process. With our analysis of the state’s solar providers, we can help. According to our research, the best […]
How Much Are Solar Panels? Based on our research and analysis of nationwide pricing data, the average cost of home solar systems is $2.85 per watt or $2,850 per kilowatt. The following table summarizes the estimated costs of solar panel systems ranging from 5 kW to 10 kW, along with net costs after subtracting the […]
Can You Install Solar Panels in an Apartment? Apartment owners or renters who want to use solar energy have fewer options due to a lack of roof space. Even if you live on the top floor of a building, the roof is likely considered a common area where you cannot install solar panels. Some apartment […]
The electricity output of photovoltaic modules depends on the direct sunlight reaching their surface. That’s why solar panel productivity is higher in sunny locations and lower in cloudy weather conditions or in places where excessive shade comes from surrounding buildings. Under identical sunlight and temperature conditions, the energy output of solar panels depends on their […]

Residential solar panels need little maintenance other than regular cleaning, but you must use suitable tools and methods to prevent damage. Generally, photovoltaic (PV) modules have simpler maintenance needs than other power generation systems since they have no moving parts subject to mechanical wear. Here are some recommendations on how to clean solar panels properly: […]
The average solar panel generates 1.5 kWh of energy each day. Solar panel productivity largely depends on rated wattage and local sunshine conditions. Electricity production will be higher on sunny days with clear skies and lower during cloudy weather or on short winter days. You can estimate solar panel power output by multiplying a panel’s […]
Yes, all solar panels lose efficiency over time due to their normal panel degradation rate. High-quality solar panels with higher efficiency rates will degrade slower than cheaper models with lower efficiency rates. Your solar installer will outline your solar panels’ expected longevity and estimates for their efficiency drops. Your installer may include additional coverage to […]
