Step 1: Initial Home Assessment and System Planning
It all starts with checking out your home. This first step is really important to see if solar is a good fit for you. A solar expert will come to your house and take a look around. This usually takes a couple of hours. They’ll check a few important things.
What they’ll look at:
- Your roof: Is it in good shape? Is it strong enough to hold solar panels? What kind of material is it made of?
- Sunlight: How much sun does your roof get? Are there trees or buildings blocking the sun? Getting the angle of the panels just right can make a big difference – you can sometimes get up to 25% more energy.
- Your energy use: How much electricity do you use each month? Looking at your past bills helps figure out the right size solar system for you. (A good amount of energy use to make solar worthwhile is often around 800-1,200 kWh per month.)
- Where to put the panels: The expert will find the best spot on your roof to put the panels to get the most sun.
This checkup tells you if solar is a good idea for your home. Sometimes, about 3 out of 10 homes have problems like too much shade. The solar expert will figure out how to deal with these problems and design the best solar setup for you.
Solar panels aren’t all the same. Some are better at turning sunlight into electricity than others. This first check helps plan a solar system that fits your needs and saves you money.
Step 2: Design and Equipment Selection Process
Once your home assessment is complete, the next step is designing your solar system and choosing the right equipment. Your solar installer will work closely with you during this phase to create an efficient system tailored to your specific energy needs and budget. Most residential solar systems fall between 3 and 11 kilowatts, with around 7.15 kilowatts being a common size.
Solar Panel Types and Options
It’s important to pick the right solar panels for your home. You can choose from:
