"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"

"Excellent service! We scheduled Plumbing Plus to replace the hot and cold cartridge's in a sink faucet and a tub pop-up drain and overflow gasket. Jared N. quickly assessed the problems. The faucet was so corroded with water deposits that it could not be dismantled to simply replace the hot and cold cartridge's. So Jared replaced the entire faucet with a high quality replacement. After the tub pop-up drain was replaced, Jared checked for leaks by looking in a 'trap door' in the ceiling below the tub that was left after the tub was replaced in an earlier remodel. Jared discovered that the entire tub drain was leaking and need to be replaced, which he did. He also corrected a problem with the drain pipe left from the previous remodel. Although the job was much more complex than expected, Jared was professional, efficient, and extremely cheerful throughout . We highly recommend Jared and Plumbing Plus"

"Never again with ASI, the White Glove Guys I just went through a plumbing problem using ASI and will never use them again. My problem started when I could hear water running in a downstairs bathroom. And found that I had water leaking out at the base of the stucco siding behind the bathroom. I called ASI and they were able to send a plumber the next day. The plumber arrives and I explain the situation to him, and we agree that the best (least destructive) way to get to where we hear the leak is from the outside. He cuts an 18-inch square hole in the stucco so that we could see the leak. The good news is that we cut in exactly the right spot to see what was going on. The bad news is that the water was leaking from the sleeve surrounding a branch of the water line that went down into the concrete slab. He tells me he can’t fix the leak, but he will take the appropriate pictures and send them to the person at ASI who does leak detection and have him call me the next day. Cost for his 30 minute visit was $225 ($450 per hour!) and all I have to show for it is a hole in the side of my house. To be fair to the plumber, he didn’t know what he would find, and had the leak been above the slab he could have fixed it and we would have gone happily on our way. The next day comes and goes with no call from ASI, so I call them the following day. They can schedule me in for three days later. I’m thinking that the guy coming is going to locate the leak and fix it, but that’s not what happened. He looked at the problem and we discussed where the possible places where the leaking line could go to. We figure there are two likely places the line goes, one good and one bad. The most likely possibility is to the ice maker in the refrigerator which is in the middle of the slab with no easy way to get to it. The other is to a wet bar sink that was removed many years ago with the line water lines capped off. He says that if the leak is in the unused sink, the water line it will just be capped and it will just be a service call like before. If they have to reroute the water line will be a one-day job which is a fixed price of $2900. Considering that we think that they are going to have to run a line to an outlet in the middle of the slab, the price appeared reasonable, so we schedule for several days later. When the plumbers arrive to do the repair, the first thing is to cap off the leaking line and determine where this line actually goes. The good news is that it isn’t the ice maker, but it wasn’t the capped off wet bar sink either. Instead, this line goes to the kitchen sink. This was the best alternative possible as almost the entire rerouted line could be run outside the house. They proceed and you can see the result in the pictures. The long line on the house turns into the house though a hole they cut in the stucco and through one cabinet and has a shutoff valve on the end of it. On the near end was a down-over-up loop of about 18 inches total to connect to the water supply. They insisted on taking lunch at the point where they just had to solder one last joint. So, after the lunch break they take five minutes to solder the joint and turn on the water to check for leaks. They got here a little before 9 am and even after a 30 lunch, it is 11:30 when they are done. So even though they spend less than half a day running this one line, they still charged the full amount. I complained to the company but their argument is that they change a fix price to protect the customer if the job goes long. The problem is that if the job goes short because they estimated the job incorrectly, the customer does not get a break. In hindsight, the job should have been reevaluated once the true destination of the water line was known and done on a time and material basis. So, the bottom line is that I paid ASI over $3100 for a little over three hours work or about $1000 per hour. I will never use them again!"

FAQs for solar panel installation projects in El Cajon, CA

The physical construction phase typically requires two to four months following the receipt of all necessary approvals. At the same time, the entire development process from initial concept to operation generally spans three to five years. Factors affecting the timeline include site conditions, workforce size, and project scope. The majority of the development period involves securing regulatory approvals, completing environmental studies, and establishing utility interconnection agreements.

Developing a solar farm requires an average of $400,000 to $500,000 per acre for equipment and installation, excluding property acquisition expenses. Based on industry averages, a six-acre installation typically supports one megawatt of capacity, capable of powering roughly 164 homes. Project economics vary significantly depending on whether land must be purchased or leased, with substantial regional variations in property values.

A solar installation can generate an average of $14,000 to $40,000 annually per megawatt, with variations based on electricity rates and contract terms. Annual maintenance expenses of approximately $15,000 per megawatt must be factored into financial projections. Most facilities operate under long-term agreements spanning 15 to 25 years, providing revenue stability throughout the project lifecycle.

A 20-acre property can support a viable commercial solar installation. Based on industry averages, this area could accommodate approximately three to five megawatts of capacity, sufficient to power 600 to 1,000 residences. This scale falls within the commercial solar farm category, offering enough capacity to achieve reasonable economies of scale while remaining manageable for smaller developers or community-based projects.
