Investing in solar panels offers several advantages. Firstly, they enable significant savings on your energy bills for both residential and commercial properties. Additionally, solar panels serve as an eco-friendly alternative to traditional generators, boasting benefits such as silent operation, absence of unpleasant odors, and freedom from the need for fuel.

Investing in solar panels offers several advantages. Firstly, they enable significant savings on your energy bills for both residential and commercial properties. Additionally, solar panels serve as an eco-friendly alternative to traditional generators, boasting benefits such as silent operation, absence of unpleasant odors, and freedom from the need for fuel.

The cost of a photovoltaic (PV) system can vary based on several factors, including its configuration; size, the quality of equipment used, and labor costs. On average, you can expect an ordinary PV system to have an approximate price tag of $10,000 before factoring in installation expenses and potential incentives.

No, it is not essential to have uninterrupted sunshine for your solar panels to generate power. Solar panels can still generate electricity on overcast days or when they are not exposed to direct sunlight, albeit at a reduced efficiency.

 

The efficiency of your solar panels on a cloudy day is contingent on the amount of sunlight they receive. On average, solar panels’ power output may decrease by approximately 20-40% under cloudy conditions.

You need not worry about snow accumulating on your solar panels, as they are designed to endure heavy snow loads. Typically, the snow naturally slides off the panels as they heat up and begin operation, eliminating the need for manual snow removal.

Solar panels typically have an average lifespan of 25-30 years. However, even after this period, they will continue to generate electricity, albeit at a slightly reduced rate.

Solar panels come with two types of warranties: performance warranties and product warranties. Product warranties typically range from 10 to 30 years. It is important to note that for warranty support, you will need to contact the manufacturer. Further details can be found in the Warranty Support and Return Policy section.

Is going solar worth it?

You can achieve financial benefits by reducing your reliance on purchased electricity from your utility provider, opting to use the energy generated by your solar system instead. Additionally, surplus solar energy can be fed back into the grid, causing your electric meter to run in reverse and potentially earn you credits.

Certainly, a solar system in the United States typically recoups its initial costs within a span of 6-8 years. The exact payback period hinges on factors such as local electricity rates, available incentives, and the upfront expense of the solar installation. Over its lifespan, which exceeds 25 years, your solar system is likely to pay for itself two to three times over.

Indeed, incorporating solar panels into your home can potentially increase its appraised value by up to 4.1%.

It is advisable to assess the presence of regions with adequate sunlight exposure and the feasibility of installing solar panels in such areas, even if they are occasionally shaded. The utilization of microinverters and power optimizers can help maintain the efficiency of a solar system, even when subjected to intermittent shading.

Payment & Delivery

PV system cost depends on various factors such as configuration, size, equipment and labor. An average system would cost about $10,000 without labor and incentives.

You can pay by credit card, Zelle or PayPal. You can also apply for PayPal credit or make an ACH payment. For large purchases we recommend using wire transfer.

First of all, don’t worry. Sometimes it happens because of improper transportation. If you received broken panels:

1. Take full-length pictures of the damaged panels

  1. Note all damages on the delivery slip and inform the freight company
  2. Fill in Damage Report Form We’ll investigate your case and take care of the replacement. Read the article to learn more about how to receive and inspect freight shipment.

Contact the manufacturer of the equipment. If you have problems with an inverter, companies like Solaredge or Fronius offer remote troubleshooting.

Solar system design

On average, you will typically require a range of 15 to 30 solar panels to meet 100% of your energy needs. For a more precise calculation, we recommend utilizing our Solar System Calculator.

It’s essential to distinguish between the DC power output of your system and its AC production. The DC power rating represents the combined power output of all the panels within your system. In contrast, AC production signifies the usable alternating current generated. Due to factors such as imperfect panel positioning, cloud cover, and energy transfer and conversion losses, the AC production is approximately 20-25% lower than the DC power rating of your system.

Over time, the power production of solar panels experiences a gradual degradation, reducing by approximately 0.7% each year. It’s worth noting that some panels exhibit slower aging rates than others. For example, top-quality panels like those from Panasonic and REC lose only 0.25% of their output annually.

We do not recommend combining different panels within the same solar system. Doing so can result in some panels underperforming and potentially lead to malfunctions in the future. Moreover, such a system may not gain approval from relevant authorities, and warranties are likely to become void.

The power rating of your chosen inverter should align with the DC power rating of your system. For string inverters, we suggest considering options such as Solaredge, Outback, and Schneider inverters. If you prefer microinverters, APsystems and Enphase are among the top choices.

Standard grid-tie inverters are designed to shut down the system when a power outage occurs, adhering to safety requirements. However, if you have a hybrid inverter equipped with battery storage, it will seamlessly transition your home to battery support, allowing your solar panels to continue generating electricity even during an outage.

Solar system installation

Professional installers typically complete the installation of a residential rooftop solar photovoltaic (PV) system within a timeframe ranging from one to three days.

The required roof space depends on your energy generation goals and the specific panels you intend to use. For instance, an average 400W panel typically occupies approximately 20 square feet. Consequently, a 6-kilowatt system would necessitate approximately 300 square feet of roof space. Opting for panels with higher efficiency ratings can help conserve space. To obtain a precise estimation of the space needed, we recommend using our Solar System Calculator.

Do I need separate mounting frames or brackets for rooftop installations? Installers employ mounting frames and brackets to secure solar panels, whether on rooftops or the ground. To determine the most suitable mounting option for your specific circumstances, we recommend obtaining a quote and consulting with our engineers.

In the northern hemisphere, it is advisable to orient your solar panels to face true south, while in the southern hemisphere, they should face true north. This alignment ensures that your solar panels receive direct sunlight throughout the day.

It’s important to be aware that solar panel production tends to decrease in hot weather. Solar cells typically experience a reduction of around 0.4% in output for every degree above 77°F. Notably, solar panels tend to be hotter than the ambient air. Therefore, on a scorching summer day, a solar panel may lose approximately 10% of its output.

If you’ve connected your solar panels in parallel, the voltage across the array will remain low, but the currents from each panel will add up. Conversely, when you connect solar panels in series, the voltage figures add up, but the overall current remains low. The configuration you choose depends on your specific system requirements.
