"The overall experience was good. Even though our roof is quirky and we have parts that are shaded, they were able to angle panels in different areas to get the maximum sun exposure. There was one glitch...the system wasn't working when we first turned it on upon approval from the electric company but once I contacted them they were quick to come out. The problem was a switch that hadn't pushed on properly and was an easy fix. We felt like they worked very hard to get the system in for us quickly and were polite and professional throughout the experience."

"My house always have an electric bill issue with the AC going all summer long and everything we used today being electronic. This issue caused me to start and look for a company that can lower my bills by installing a solar panel system or any other type of a solution. Since switching to nuclear power was frowned upon by my neighbors and the federal government, I decided solar panels would be worth a try. After looking and researching on several companies, I decided to meet and talk to the representative from Landmark construction and energy crew. Ezra and his staff over at Landmark Construction were great. Ezra walked me through the whole process and he was completely honest and accurate with the pricing and time schedule. The system that he recommended me was a 3.1 kW system with panels on the roof of the house. He had the time to tell me how will it go and what will be the final results after the system will be fully installed and working. I have a past experience work in the construction industry and I know competence and good workmanship, these guys know what they are doing and do it well. I was very satisfied with the work and with the system that they installed at my house. My utilities bills came down as Ezra said they will. I would recommend them to anyone considering solar power."

"David Flores.Ontario.CA. - Our sales guy Daniel was personable and informative. He was easy to get along with. I chose NRG because of the price and the customer service. We got 4 quotes from different solar companies and NRG stand out the most because they were more family oriented and also been in business for a long time. Tiffany whether it was email text or phone she immediately got back and answered all my questions to my satisfaction. Installers were professional and installed 16 panels and panel upgrade in one and half day. Robert came to my home and checked the quality of work from the techs and gave me useful tips on how to use my solar efficiently. Great guy and shows great customer service skills. I would recommend this solar company to anybody trying to get quality work done."

"The young guy who did the work was prompt and professional, but not well trained. He power washed my patio BEFORE blowing the leaves and sticks off my roof, so all the debris landed on my just cleaned patio, and he didn't follow up to clean it off.
He forgot to do the garage door and was all packed up when he asked me to inspect, so I just let it ride.

FAQs for electrical wiring or panel upgrade projects in Williams, CA

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
