Finding out how much wattage, or power, your home needs to run all appliances and systems, gives you a good idea of the amount of power your solar system will need to produce.
For the state of Texas, you can start by finding your annual kWh usage. Most bills show a graph on them or if you are in a deregulated area then you can go to www.smartmetertexas.com. Determine the annual kWh and then divide that number by 1.5. This will give you an approximate estimate of the number of watts you will need to offset your bill.
12,000 kWh / 1.5 = 8,000 watts
The range of price per watt to install solar panels in Texas is $3.20 – $3.55/watt (after tax credits). So, you can then multiply the 8,000 watts by the price per watt, or $3.55 x 8,000 = $28,400.
If you don’t want to do all the math yourself, no problem. Check out our solar panel calculator for an accurate estimate.
