"I had an issue with our solar panel not producing any electricity so I called and left message for Garrett from Sunlux. Not only did he call me back the same day, but he basically diagnose the problem over the phone and sent someone from Sunlux to come to my house the next business day to confirm diagnosis that we had a bad inverter. A few hours later that day Garret called not only to schedule an install of the new inverter, but to my surprise he also said that because we were having problems with pigeons living under the solar panels that he would install critter guard to prevent the pigeons from going underneath the panels for no charge. I would highly recommend Sunlux for their professionalism as well as their great customer service."

"We began the process with SunPower when a representative knocked on the door and asked if we were interested in exploring solar power. After this we were put in touch with Arvin, who guided us through the entire process and was thorough, transparent, helpful, and responsive. First, Arvin met with us in our home for over an hour exploring all the details of various options including PPA (power purchase agreements) and financing. After we expressed initial interest during this meeting, SunPower sent a site inspector to our home to analyze our readiness for a solar panel installation. After this, we stayed in touch with Arvin while exploring the details of our home’s solar power system. Initially, we were hesitant about the idea of a PPA since we wouldn’t own the panels that were on our roof. Once Arvin explained the details of how the PPA works, including provisions for if we do construction on our roof or move to a new home, we became much more comfortable. We ended up choosing to go with a PPA because we liked the idea of paying only for the power being produced, rather than for the equipment itself. The proposed system of solar panels was projected to cover 90% of our home’s monthly energy needs."

Highly recommend OC Solar for their outstanding support and dedication!"

"We had such a great experience with Solar Repair! Before starting our project we spoke and met with several other providers and did a lot of research on our own. From beginning to end the entire team at Solar Repair treated us with the utmost care and respect. Although they are still a fairly new company the amount of knowledge and information they gave us was times 10 compared to the others who have been around a lot longer. The information resulted in major savings and much better rebates and credits. Additionally, we ended up with better quality Panasonic Solar Panels and a great Enphase Battery Storage System. Again, the entire team was GREAT! Always taking our calls or calling us back immediately. Believe, me we called a ton and had a ton of questions!!! Thank you Garrett, Markie, Luis, and Steven you really made us feel like family!"

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

"Our roof was in bad shape and we needed to have it replaced. I had gotten estimates and decided to go with Home Pro Remodeling. Emil and Brian were our contact people for the project. Emil was very professional and paid attention to our concerns. He worked with us through the entire project to our complete satisfaction. Brian is extremely courteous and helpful as well! The project went very smoothly, was completed before the initial project end date, and the results were beyond our expectations. The job turned our beautifully! Our new roof looks FANTASTIC! Our neighbors have commented to us how great it looks. We are very pleased with our experience with Home Pro Remodeling and would definitely recommend them."

FAQs for solar panel installation projects in Ontario, CA

If you experience frequent power outages, want to become more energy independent, or aim to reduce your reliance on the grid, investing in a solar battery system can be worthwhile. With a solar battery, you'll have backup power day or night, even if the local grid fails. However, to power larger appliances or ensure you have energy for longer periods, you'll need to invest in multiple batteries. While the upfront cost is higher, many homeowners find the added peace of mind to be well worth the investment.

Solar battery storage capacity is measured in kilowatt-hours, which directly indicates the amount of energy the battery can store. This measurement determines how long essential appliances will continue operating during an outage. A clear understanding of capacity helps in planning the overall system size to ensure effective backup power and to maintain optimal performance even as the battery ages.

Determining the correct size for your solar battery system requires evaluating your monthly energy usage. Start by reviewing your utility bills to identify your average consumption, and then match the battery’s kilowatt-hour rating to cover essential loads. Consulting with a solar professional ensures that the system is sized to deliver continuous backup power, meeting both immediate and future energy needs.

A solar battery's lifespan ranges from five to 15 years, and its durability is affected by battery quality, charging frequency, and environmental conditions. Regular maintenance and proper usage are key to maximizing longevity. Monitoring your system, following manufacturer guidelines, and scheduling routine inspections all help ensure that your battery performs reliably throughout its service life.
