Depending on the electric vehicle you purchase, the additional electricity usage can vary. For example, the Tesla Model 3 averages about 250Wh/mile so for 12,000 miles, it will use about 3,000kWh/year or 250kWh/month. The Tesla Model S averages about 350Wh so for 12,000 miles, it will use about 4,200kWh/year or 350kWh/month.
Pingo Solar has experience installing on all types of roofs: from flat roofs to comp shingle to clay tile to standing seam metal roofs. The only roof type solar modules cannot be installed on are wood shake shingles, which are considered a fire hazard.
Even though your main electric panel may be old, depending on the solar system size, it may be solar ready. If you upload a photo of your main electric panel, our engineers will review and let you know whether you will need to upgrade it.
Once in a while, you may experience an internet outage or disruption which affects the monitoring. If the monitoring stops showing production, don't worry. The solar system is still operating normally 95% of the time and this can be fixed very easily. If we installed a cellular kit and your monitoring is down, there may be an issue with the local cell towers in the area. The monitoring will correct itself within a couple of days once the cell tower issue is resolved.

If your monitoring is connected to your home wi-fi, there may have been a disruption with your internet. To resolve this, reset the two white TP Link units by unplugging and plugging them back in. One unit can be found connected to the inverter and the other unit can be found connected to your home internet router.
A battery storage system can benefit you in a couple ways. The main reason to purchase a battery would be for back-up power during blackouts or brownouts. A battery can also help in shaving peak-time usage. Please contact us to learn more about battery storage.
During a blackout or outage, you will not be able to use your solar power unless you have battery storage installed. If you do not have a battery installed, the solar system will automatically shut off through the built-in rapid shutdown system as a live system can cause fatal injuries to the utility workers.
Yes. While the production will not be at full capacity, your solar system will still produce on rainy or cloudy days.
The seasonal rains California receives is usually enough to give the solar modules a nice clean. However, if you live in a dusty area such as Bakersfield, we recommend a professional cleaning to provide optimal production. We can arrange a professional solar module cleaning company to clean your modules as part of our comprehensive solar package.
String inverters and microinverters are two types of inverters that convert direct current (DC) energy to alternating current (AC) energy that is used in the home.

Microinverters are installed one per solar module on the roof. The benefits of microinverters include minimal disruption from shading and module-level monitoring. Since each solar module will have its own microinverter, if one module is shaded due to a tree or chimney, the other modules will not be affected unless the shade is covering that module as well. Additionally, you will be able to see each module's production through monitoring. The downside of microinverters is the potential to overheat and degrade production. Since microinverters are installed on the roof, where it can get upwards of 140° F, this can negatively affect your system's production.

String inverters are the most common type of inverter and are usually installed next to the main electric panel. The benefits of string inverters include reliability and cost. Since string inverters are usually mounted on the exterior wall rather than on the roof, it is more reliable and are less prone to overheating. However, unlike microinverters, if there is shading on one module, the group of modules that are connected to each other in a series, or string, are affected as well and you will not be able to see module-level production through monitoring.

A third option combines both a wall-mounted string inverter and power optimizers, which "optimize" the DC power generated by the individual solar modules. The benefits of this option include the reliability of string inverters and functionality of microinverters. The inverter is less likely to overheat, unlike microinverters, since it is not on the roof. Additionally, since the optimizers are installed one per solar module, shading on one module will not affect the others. You wil also be able to monitor each module's production, just like microinverters.
The average turn around time, from signing to receiving permission to turn the system on from the utility, is about 45 days. However, the process may take a little longer, depending on HOA review times, if applicable, and permitting times by the city or county. The actual installation usually only takes about two to three days.
Purchasing rather than leasing a solar system is always the better option. Leases were popular 10 years ago when the cost of solar was very high, but with solar prices dropping drastically, you will see a greater benefit purchasing the system. With leases, you are not eligible for the 30% tax credit and the leasing company will own the system, not you.
Homeowners who purchase a solar system will receive a 30% federal incentive tax credit (ITC) to help subsidize the cost of solar. However, the ITC will drop to 26% starting January 1, 2020 and down to 22% on January 1, 2021 and is expected to go away completely starting in 2022.
You will need to fill out IRS form 5695. While claiming the tax credit is easy, we recommend consulting a tax professional or accountant to fill out the form properly.
Yes. You may be eligible for a 12 year, no prepayment penalty loan through Wheelhouse Credit Union or you may be eligible for a Property Assessed Clean Energy (PACE) program such as Ygrene or HERO. You can also select to use your own lender.
Yes. Every month, you will receive a bill from the utility company showing any excess power you've sent to the grid or any additional power you've used from the utility. Additionally, there will be a monthly minimum charge that you will need to pay for being connected to the grid, which is usually about $10. Every 12 months, you will receive a true-up bill, which aggregates the power you've sent to the utility company and the power you've used from them. If you used more power from the utility over the 12 months, there will be a balance due. If you sent more power to the utility than you used from them, you will receive a credit.
If your solar system overproduces and you send excess power to the grid during the 12 months, you will receive credit at retail rate, which rolls over to the following month. At true-up, if the excess power that was sent to the grid is greater than the power used from them, you will receive credit at wholesale rate.
The number of modules that goes on the roof will depend on your energy usage and roof space. Most homes will have enough roof space for the solar modules without any issues. However, if your roof space is limited, we can install higher wattage modules to minimize the number of modules needed.
Studies have shown that solar systems that were purchased increase the property value of the home. Since the new homeowner will have a reduced energy bill or no bill at all, it's easy to see why. However, leased solar systems have a negative impact on the property value since the new homeowner will have to take over the lease, making it more difficult to find a buyer. This is another reason we recommend purchasing a system rather than leasing it.
At Pingo Solar, we are dedicated to providing the best quality products and service at extremely competitive prices. We are able to do this by eliminating middlemen and streamlining our processes. Most solar companies will send a team out to your home before providing you with an accurate proposal, incurring overhead. With our online mapping tool and propietary software, we are able to accurately overlay the modules on your roof to show you what it will look like. This eliminates the need for us to visit your home early on in the process. If the proposal looks good and you are ready to move forward, we will send our site survey team out to double check the measurements once you have reviewed and signed the solar agreement.
