The average payback period for a solar panel installation can vary based on factors such as location, system size, energy consumption, panel technology and available incentives. On average, payback periods range from 5 to 10 years. This means that after this period, the cumulative savings on energy bills typically offset the initial investment.
Get ready to save money on your electric bill each month while also helping save the environment. Your family’s energy usage and the size of your solar energy system installed will determine the size of your savings.
The amount you save with a solar energy system depends on several factors. These include your current energy consumption, local electricity rates, system size, available sunlight, and any incentives or rebates. Generally, home solar panels can significantly reduce or even eliminate your electricity bills. Over time, the savings can accumulate as you generate your own clean energy. Our Partner installers will help you choose the right solar technology and can help estimate potential savings based on your specific circumstances.
Your SunPower system was designed with typical soil accumulation in mind, and seasonal rains are usually enough to adequately clear any soil or dust that might accumulate. We strongly recommend that you do not go onto your roof for panel cleaning or inspection. If severe soiling occurs and you feel it is absolutely necessary to clean the panels, you can clean them by spraying them from the ground with a standard garden hose. We recommend that homeowners only clean panels early in the morning or late evening rather than when the sun is at its peak or when the panels are warm.
To clean a module, wash with potable, non-heated water. Normal water pressure is more than adequate, but pressurized water up to 100 bar may be used. Fingerprints, stains, or accumulations of dirt on the front surface may be removed as follows: first rinse off area and let soak for a short period of time (about 5 minutes). Re-wet and use a soft sponge or seamless cloth to wipe glass surface in a circular motion. Fingerprints typically can be removed with a soft cloth or sponge and water after wetting. Important things to keep in mind:
As a rule, stay on the ground. Never get up on your roof without a secure ladder and proper fall-protection equipment. Turn off your system before you start cleaning. Consult your local Installer if you need help turning off your system. As a rule, avoid using hard, or mineral rich, water. It can damage panels over time. If your area only has hard tap water, you can buy an inexpensive water-softening hose attachment to filter out minerals. Otherwise, you can use distilled or de-ionized water.
Use soft brushes and squeegees. Do not use harsh cleaning materials such as scouring powder, steel wool, scrapers, blades or other sharp instruments to clean the glass surface of the module. Use of such materials of cleaning without consultation will invalidate the product warranty.
Clean early in the morning or in the evening when the panels are cool. During the heat of the day, water and soap can evaporate quickly, which risks smearing the soap and dirt.
When using a high-pressure water nozzle, don’t get close to the panels. While they’re extremely durable, you don’t want to damage them.
Do a monthly visual inspection to look for any dust buildup. Also, you can watch your bill for any noticeable drop in efficiency. Only then should you worry about cleaning. Even then, in most cases, nature is going to clean them for you.
Don’t expose yourself to any risk. If you have any doubts about your ability to safely clean your panels, hire a professional.
SunPower Maxeon panels also deliver greater peace of mind, having earned the trust of experts by being more reliable and durable - and backed by our industry-leading Complete Confidence Warranty. Not only is this warranty stronger, but unlike most conventional warranties, it is based on actual field-testing data. For example, the power warranty promises no more than a 0.25%/ year power drop. This is backed by a study of more than 230MW across 149 actual global sites using a methodology developed in collaboration with NREL. We also know from actual field data that only 0.005% or 1 in 20,000 SunPower Maxeon panels have been returned under warranty. Lastly, SunPower Maxeon panels are built with our customers in mind, which means higher sustainability standards and more elegant design aesthetics than Conventional Panels. SunPower Maxeon panels have pioneered sustainability efforts in solar manufacturing, and have been recognized with the prestigious Cradle to Cradle Certified™ designation for direct current (DC) panels. The Cradle to Cradle designation demonstrates the products' quality based on rankings of material health, material reutilization, renewable energy use, water stewardship, and social fairness.
SunPower Maxeon panels were also the first solar panel to disclose its ingredients through the Declare label. In March 2020, our Mexicali, Mexico manufacturing facility was re-certified by NSF Sustainability as Zero Waste to Landfill – and remains the only solar panel manufacturing facility to achieve this. The certification means that this facility diverts more than 99% of its waste, with 1% or less going to landfills.
br> The back-contact cell design of SunPower Maxeon panels also delivers an uncluttered and elegant design aesthetic – with panels available in black and white backsheets. This has made SunPower Maxeon panels the panel of choice for architects and designers.
SunPower is known for its commitment to quality and service, offering at 30-year Complete Confidence Panel Warranty. Given their track record and the advanced technology used in the Performance panels, businesses can expect more energy and reliability over traditional front contact panels.
In single-phase, 10 microinverters can be connected. In a three-phase installation, up to 30 microinverters can be connected on a single 20A three phase circuit breaker. Larger systems can be constructed with multiple AC branch circuits.
SunPower Performance solar panels help organisations minimise up-front project costs. Their enhanced reliability and durability mean fewer maintenance issues and longer panel lifespan, leading to long-term cost savings. The panels' superior efficiency also ensures optimal energy production, reducing energy bills over time.
The Enphase three-phase Q Cable allows balanced and automated power management of each phase. Alternatively, when using three single-phase cables, care must be taken to balance the phases by installing a similar number of panels on each phase.
The Envoy-S communications gateway can also provide phase imbalance monitoring to ensure authorised limits are not exceeded. The Envoy is able to manage PV power production at the microinverter level to maintain balance within set limits.
If an issue is detected via the Enlighten monitoring platform, please contact Enphase Customer Support. If the issue is related to the microinverter, Enphase will provide any service required under their warranty coverage. If Enphase determines the issue is related to the panel, the service will be transferred and supported by Maxeon Solar Technologies under the appropriate SunPower panel line warranty.
There are a number of methods but often cell customers use a soldering iron. Also we have an instruction guide that explains how to connect the cell and tabs so feel free to contact us from the inquiry page.
