How many solar panels to power a tiny home.

Keep in mind that the amount of power your solar system can produce depends on how much sunlight your roof receives and your location. If we used 300w panels seven solar panels would provide all of the power we need. This assumes an average sized solar panel of around 300 watts which would generate around 4 500 watts of power from the sun. While this certainly won t support central a c or heat it may allow for most other appliances especially if a tankless water heater is used.

The average american home needs 14 36 solar panels to power their home if you live in a sunnier state less solar panels are needed to generate the electricity your home needs more efficient solar panels means less solar panels are needed high efficiency panels are necessary when installing solar panels on a small roof. Solar panels are usually able to produce 250 to 400 watts of power. A 10kw solar system which consists of 40 panels can produce an average of 14 000 kwh per year. Say your tiny house is exposed to 5 hours of sunlight a day and your solar panel is able to produce 250 watts you ll compute it this way 5 x 250 watts.

You will need a roof space of about 680 sq ft for a 10kw system. The number of panels you need for your house depends on factors like location and panel performance. An average homeowner needs 28 to 34 solar panels to fully offset their electricity bill with solar. Based on the averages a tiny house with 7 solar panels will generate about 15 75kwh per day.

A grid tied inverter would convert the dc power from the panels to ac power for your tiny house. This would cover all your power needs including some heating and cooling but require you to have a gas cook range and a propane heated hot water heater.
