The sun rises every day. That's why solar power is a completely renewable, reliable, clean energy source. It reduces our reliance on dirty sources of power such as oil, coal, and natural gas, which produce harmful emissions affecting our health and environment.

We have been delivering on a vision to create a planet run by the sun and provide people with affordable, reliable, clean energy. Residential solar energy systems represent an investment in the future of the planet, conserving non-renewable energy sources and protecting the environment.

In addition, solar panels and home batteries are becoming more affordable, accessible, resilient, and efficient. They provide peace of mind and energy security for households when the power goes out or the next storm strikes. Unlike those from your utility, Rainbow customers pay predictable, affordable rates for 20 to 25 years. With home solar, you get to control your energy future.

A lot of things affect how well-suited your home is for solar, including where your home is, the angle of your roof, how much shade it gets throughout the day, and how old your home is.

Our solar advisors can help you determine if your home is a good fit for solar at the moment. They'll run a custom analysis of your home with our proprietary solar design technology,  and they'll get a sense of your energy needs.

Your historical electricity usage allows us to design a custom solar system that is the right size for your home.

Electricity usage varies from person to person and from season to season. That's why we request a full year of your electricity bills so we can build a system that's right for you. Your sales consultant is trained to review a year's worth of usage data so we can get the full picture. Energy usage can change with the seasons so we look at 12-months of data to best understand your home's usage patterns and needs.

Every household is different. When determining the number of solar panels your home needs, consider the following questions:

Check your electric bills to see how many kilowatt hours (kWhs) you use throughout the year. We’ll go over this with you in detail during your free solar consultation to figure out just how much power your panels will need to produce.

What’s your climate like? The number of panels you need depends on how much sun reaches the ground where you are.

How much direct sun hits your roof? Shading, which direction your roof faces, and any aesthetic preferences you have can impact how big your system needs to be.

Theoretically speaking, you can connect as many SOLS in serial(but not in parallel) as you want.

However, the effciency of the machines will be seriously compromised(The energy consumption of the inverters grows with the number of the connected machines.) As a result, we do not recommend to connect more thn 3 SOLS in serial, an it is necessary to fully charge every SOL before you connect them  together. Moreover, connecting SOL in serial will not increase the rated output, but will expand the capacity.

Yes, it can. You need confirm the item has some power.

No, because SOL is made of by lithium battery. According to the international Standards & Regulations for the Transportation of Hazardous Materials, no lithium batteries with 100 watt hours may be allowed in carry-on bags.

We are very sorry, but it cannot be used to jump start a vehicle. However, it can be used as power supply for automobiles. SOL can charge the lead batteries of your car through the car charge cable included in your SOL parcel.

No, we are not doing solar panels, but we can recommend suitable solar panels. And if you need it, we'll be happy to buy it for you and send them to you with SOL together.
