How to Choose a Solar Energy System Supplier
Solar energy systems convert sunlight into electricity using photovoltaic (PV) cells. The PV cell’s internal electric field creates moving charges that generate electricity when a current passes through them.
Diversifying raw material and solar PV import routes helps reduce supply chain vulnerabilities. This can be done through policy tools like tax incentives and finance support policies.
Cost
There are a number of factors that influence the cost of solar energy systems. These include the type of panel and its efficiency, the solar energy system supplier racking system, the inverter brand, and the installer’s experience. Fortunately, prices for solar hardware are continuing to fall due to advances in technology and increased competition.
Another factor that influences the price of a solar energy system is the system size. Generally, larger systems have lower cost per watt than smaller ones. However, it is important to remember that a higher wattage system may require more panels. This is why it is a good idea to consult a professional to determine how many panels you need for your specific situation.
Non-hardware costs, or soft costs, are also a factor. These costs can include a variety of items, including permit fees, insurance, and financing. Solar companies often build in a markup on these soft costs to cover their own expenses and attract customers.
Ultimately, the best way to estimate your solar costs is to compare quotes from multiple vendors. This is easy to do through EnergySage’s nationwide online Solar Marketplace. The marketplace connects you with local solar companies, who compete for your business by providing custom solar quotes. These quotes include system prices BEFORE the 30% federal tax credit. The quotes also account for other discounts and rebates available in your area.
Quality
As with other consumer electronics, solar energy systems require high-quality components in order to perform as expected and deliver the best value. Solar companies earn points for offering quality equipment, including panels, inverters and batteries. They also get rewarded for extending solid product and workmanship warranties. A strong warranty can help offset the upfront cost of a solar energy system, and can ensure that you receive maximum benefits from your investment.
Solar installers also earn points for delivering top-notch customer service, including virtual consultations, an app to monitor solar production and 24/7 support. Companies that offer these features gain a higher score in our review, as well as for a meaningful level of price transparency and a strong track record in the industry.
Ultimately, the best solar energy systems are manufactured by vertically integrated companies that control every step of production from conception to delivery. This allows them to make assurances to consumers that their product will meet or exceed the industry’s standards. They also utilize the highest-grade silicon available to produce their products, which helps ensure that they last longer and provide reliable energy to customers. In addition, their solar energy systems are built using robots, which reduces the chance of human error during installation and ensures a uniform project.
Installation
When choosing a solar installation company, it is important to obtain quotes from several companies. You should also determine whether the contractor has an Illinois Distributed Generation Certified Professional and ask for references from previous customers. A quality installation will provide optimal energy production and longevity for the system.
A good installer will evaluate your property and home energy needs before designing a solar power system for you. They will also help you navigate financial incentives and ensure that your system meets all local code requirements. Additionally, they can recommend any necessary repairs or improvements for your solar system to function at its best.
Once the design is finalized, the installer will begin to install the solar panels and any other equipment in your house or building. They will also make electrical connections between the solar battery (if you opted for this feature), inverter, and your main power panel. outdoor led solar lights They will also set up your utility interconnection and net metering, if applicable.
Make sure that the solar installation company is familiar with your local permitting and interconnection processes. Depending on where you live, these processes can be lengthy and complicated. It is also important to clear any obstructions from your roof and yard to optimize sunlight exposure for the solar panels. The solar company should also give you a comprehensive list of warranties and instructions for operating the system.
Maintenance
A solar energy system supplier should provide their customers with clear and transparent maintenance procedures. These should include cleaning, inspections, and repairs. These steps are a critical part of the installation process and will help to safeguard the customer’s investment and build brand trust.
Solar panels require regular cleaning to prevent dust, bird droppings, and pollen from clogging them. This can affect their performance and decrease the amount of energy they generate. A visual inspection can identify any physical damage that needs to be fixed. Moreover, a professional can use an app to monitor the health of solar panels and alert customers if they are losing efficiency.
In addition to regular cleaning, the solar panel installation company should inspect the system’s electrical connections and wiring. This will ensure that the solar power system is properly connected to the home’s electrical grid. Moreover, it will ensure that the solar system does not draw more amps than the existing circuit can handle.
A thorough system check will identify any faults and optimisation potential in the PV system. This will allow the installer to address these problems immediately and increase the energy yield. The system check will also include the evaluation of manufacturer specifications, grid operator regulations, and local weather conditions. It will also determine the optimal solution for a PV system.
