How to Compare Solar Quotes
Gathering Usage Information
“What is your annual energy usage in kilowatt-hours (kWhs)?”
- There are a few ways to find out:
- Add the total of twelve months of kWhs from your utility bill.
- Log in to your utility account and download your usage for the past twelve months.
- Send twelve months of utility bills to the consultant, who will determine your total kWhs.
Next, your consultant will determine how many solar panels your project requires. And that amount depends on the panel’s wattage(W). So, if your consultant is quoting an 8kW system using a 400W panel, your project would need 20 panels.
1kW = 1,000W
8kW = 8,000W
8,000W ÷ 400W = 20 panels
It’s critical to compare quotes apples to apples on estimated production. You may receive a quote that is substantially less than others. If so, check the system size to ensure it’s the same as competing quotes.
The estimated production is usually very accurate if the system design is in direct sun with no shading. And your quotes will be similar in cost.
However, the estimated solar production can vary between quotes if you have shading from trees, hills, buildings, or other objects. The difference will depend on how much shading there is and whether or not it was even factored in.
