How do I calculate how many solar panels I need?

You can calculate how many solar panels you need by multiplying your household’s hourly energy requirement by the peak sunlight hours for your area and dividing that by a panel’s wattage. Use a low-wattage (150 W) and high-wattage (370 W) example to establish a range (ex: 17-42 panels to generate 11,000 kWh/year).

The more peak sunlight your home gets, the more solar energy it can generate. Getting at least 4 hours of peak sunlight is considered best for solar rooftop panels. However, even Alaska, a state that gets less than four hours of peak sun, still can benefit from solar power.

What orientation is best for solar panels?

Direction. In the northern hemisphere, the general rule for solar panel placement is, solar panels should face true south (and in the southern, true north). Usually this is the best direction because solar panels will receive direct light throughout the day.

Do solar panels need an inverter?

Solar cells require an inverter because their DC output needs to be transformed into AC. The main reason for this is that most of our home appliances need electricity in AC form to function correctly. So, the inverter does the conversion job. It receives DC electrical energy from solar cells.
