"Baker enables Southern California homeowners to generate, manage and use their power to save money, be comfortable and protect the planet. We intelligently bring together home comfort and energy solutions like solar, battery storage, roofing, EV charging, heating and air conditioning to help homeowners save money and help create a resilient and clean energy future."

"I’m so excited today. Baker Electric is completing the installation of my Tesla battery which will connect to my solar system. The entire process has been seamless. From the very beginning I received informative emails from the office keeping me up to date about required permits, process needs and what to expect next. As luck would have it, I also received a call that the workers could come to my home a day earlier than I was promised and they asked if I wanted them to start early! I knew when to anticipate their arrival and what they would need to get started on the project. Before the workers began the installation of my battery, they reviewed what the two-day process would look like and when to expect my electricity to be turned off. As they worked, they kept the work area clean, reminding me where they were in the process, and when the electricity would be off. No matter how many questions I asked, they acted like responding to me was a priority and didn’t walk away unti"

We know that in the summer heat and the winter cold, homes in the inland empire need help keeping families comfortable. We would love to discuss how our roofing products could benefit you and your family. Give Semper Solaris Construction, Inc., a call today so we can help you pick the best roof for your home.

"Semper Solaris Battery Installation Review I hired Semper Solaris to design and install a battery system tailored to my home?s needs, and I provided them with all necessary data upfront. Unfortunately, their proposed solution was not engineered appropriately and failed to meet expectations (I found out afterwards, since I am a Radio/Radar engineer, not a solar power engineer). The installation designers wanted to place the batteries in an unsuitable/ridiculous location and used a system that unnecessarily rewired my power panels, creating significant electrical complications. (As an electrical engineer, I recognized these choices as poor practice). After installation, I had to resolve account and software issues directly with Tesla, only to learn that the system had been improperly sized. Semper Solaris did not deliver the professional expertise I relied on. "

FAQs for solar panel installation projects in El Cajon, 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.
