"My April, 2019 electric bill was $1.05. I am amazed at the solar production of my YellowLite system in NE Ohio. We installed 20 solar panels (6.2 kW) in July, 2018 after learning that some friends used YellowLite and were happy with their installation. The company was helpful teaching us the ins and outs of solar power before we made our purchase. YellowLite handled all the permits and paperwork with our electric company so we didn't have to. The installation crew and electricians did a great job. The SolarEdge app is a great way to see how much power we're generating on any given day. We picked YellowLite because they have a long track record of solar installations. We're already planning to buy more panels sometime in the future as we've since bought an electric vehicle. Solar power is essential to a clean environment and we're happy to invest in a cleaner world for future generations. YellowLite did a great job for us."

"Tim, the owner, came over to review what we needed. He ordered a new inverter, was very communicative and installed the new inverter once it was received. We could not be happier with the service Tim and Sunivation Solar provided for us, and we will not hesitate to call them back should we need anything again. Tim was extremely kind, very thorough and just did an excellent overall job. Thank you!!"

"We bought a house that had a generator on the property. The previous owner bought it through Kapital Electric and had an annual maintenance agreement with them, so we sort of just "took over" and continued using them for maintenance.
The maintenance went well - there wasn't really anything wrong with the generator, so the technician just inspected everything, changed oil and spark plugs. He did a good job though of explaining how things work, since we weren't involved in choosing the generator and weren't around for the installation - basically, didn't know much about it.
The only blemish was the initial scheduling - the first time when we had the appointment scheduled and I took time off work to be there, the technician was delayed at previous appointments (as it turned out later) and never made it to our house. And no one called us to let us know, nor did anyone answer the phone when we tried to call the business towards the end of the window when they were supposed to come.  On the first day for which we wanted to have the appointment rescheduled no one was available, so we rescheduled for a week later from the original date. After that though, everything went fine, with email reminder/confirmation from them a couple of days before the appointment and a courtesy call from the technician when he was already on the way. So I'd assume that the initial scheduling incident was a hiccup, and would still use them in the future.

"Fantastic! Steve, Cody and the guys were absolutely the best to work with. We chose Solar Plus USA over a couple other providers as a result of Steve coming over to see the house in person early on (most solar installers will only look at a Google Maps picture), being very knowledgeable about the materials and the process, and presenting the best plan for the solar panel layout. Steve was on the level the entire time, never overselling anything or making promises he didn't keep. Permitting and installation went as smoothly as possible. We would absolutely recommend Solar Plus USA to anyone interested in installing solar panels."

FAQs for solar panel installation projects in Naperville, IL

A single Tesla Powerwall provides backup power for essential home circuits for approximately one day during an outage. This duration varies significantly based on which appliances and systems you're powering. Critical loads like refrigeration, limited lighting, internet equipment, and a few outlets might draw two to five kWh daily. With 13.5 kWh of usable capacity, careful energy management is necessary for extended outages unless you have solar panels to recharge during daylight hours.

A Tesla Powerwall can power most residential air conditioners, as its 5.8 kW continuous output handles the three to four kW requirement of standard AC units. However, running air conditioning substantially increases energy consumption, potentially depleting a single Powerwall within several hours. For meaningful climate control during extended outages, multiple Powerwall units are recommended. Solar panel integration helps replenish the batteries during daylight hours, extending your cooling capabilities.

Tesla Powerwalls qualify for the federal Residential Clean Energy Credit, which offers a 30% tax credit through 2032, followed by 26% in 2033 and 23% in 2034. This represents a tax credit (direct reduction of tax liability) rather than a deduction. To qualify, the system must be charged primarily from renewable energy sources. Additionally, many states and utilities offer supplemental incentives that further reduce effective costs. Consult with a tax professional regarding your specific eligibility and filing requirements.

Unlike conventional generators that require fuel, maintenance, and produce noise and emissions, Tesla Powerwalls operate silently and automatically without ongoing fuel costs. While generators can run indefinitely with refueling, Powerwalls have capacity limitations unless paired with solar recharging. Traditional generators cost less initially but require regular maintenance, testing, and fuel storage. Powerwalls offer additional daily benefits through energy bill management and smart home integration features that generators cannot provide, making them multifunctional investments beyond emergency backup.

Tesla Powerwall systems require minimal ongoing maintenance compared to other backup power solutions. Unlike generators with moving components requiring regular servicing, Powerwalls function virtually without mechanical intervention. The manufacturer recommends keeping the unit's surroundings clean and ensuring proper ventilation. For systems paired with solar panels, periodic panel cleaning (costing between $295 and $625) helps maintain optimal charging efficiency. The system conducts automatic self-diagnostics and receives software updates remotely, with most potential issues identified and addressed through Tesla's monitoring capabilities.
