How many watts of solar do I need?
Divide your average hourly wattage requirement by the number of daily peak sunlight hours for your area. This gives you the amount of energy your panels need to produce every hour. So the average U.S. home (900 kWh/month) in an area that gets five peak sunlight hours per day would need 6,000 watts.

What are the 2 main disadvantages of solar energy?
Disadvantages of Solar Energy Cost. The initial cost of purchasing a solar system is fairly high. Weather-Dependent. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops. Solar Energy Storage Is Expensive. Uses a Lot of Space. Associated with Pollution.
Why is my electric bill so high with solar panels?
Solar power systems are finite resources—they can only produce so much energy consistent with the size of the system, and most utilities limit system size to the historical energy usage average at the site.
What is the solar tax credit for 2021?
The federal Investment Tax Credit (ITC) In 2021, the ITC will provide a 26% tax credit on your installation costs, provided that your taxable income is greater than the credit itself. For most homeowners, this effectively translates to a 26% discount on your home solar system.
Why you should not get solar panels?
Low Energy Costs. For residential solar systems, generally, it is not a good idea to change your off-peak hot water across to the main phase of your house to then run off solar power. Because the tariff on your off-peak is so low, it will take much longer than the average 3-5 years for the system to pay for itself.
