pv magazine is developing a comprehensive guide to home solar installations, aimed at those interested in installing solar panels but new to the market and looking to make informed decisions. Weve consulted with associations, installers, and industry experts in the worlds major solar markets to compile best practices and tips that are applicable to home solar installations anywhere in the world. This first part of the series aims to help homeowners interested in adopting photovoltaics identify the best installers on the market. Considering installing solar panels on your home but unsure how to proceed? Installing home solar systems can offer numerous benefits, including lower energy bills, increased property value, and, in some countries, the ability to sell excess energy back to the grid. However, its essential to have the right information before committing to an installation to ensure its a worthwhile investment. This first article in a four-part series will cover key points to consider and common mistakes to avoid during your search for an installer. Key tips for finding the right solar installer When looking for an installer, its important to consider their experience, reputation, and qualifications , ensuring theyre properly licensed, insured, and have experience working with the type of solar system that best suits your home. Camille Tarrieu, a residential solar specialist at the Syndicat des Energies Renouvelables in France, emphasizes that its crucial to confirm that the installer will handle all administrative processes. Installing home solar systems requires compliance with local regulations, and depending on the country, permits or authorizations for grid connection may be required. Reputable solar installers typically handle these procedures, but its important to confirm. Transparency is equally critical. Cecilia Bergamasco of Italia Solare suggests that when receiving a quote from a potential installer, you should make sure each cost item is itemized to avoid surprises later. This will also give you a better understanding of what to expect during the process and help determine if an offer seems too good to be true. “A good installer not only offers a competitive proposal but is also willing to explain in detail the system features and the various financing options or incentives available,” adds Bergamasco. Several sources, including Joshua Buswell-Charkow, deputy director of the California Solar & Storage Association, and Rodrigo Sauaia, CEO of Absolar in Brazil, recommend that homeowners get quotes from at least three qualified installers to compare bids and lead times . While price will naturally be a major consideration for most potential buyers, several sources consulted by pv magazine emphasize that the quality of the solar system should not be overlooked , as this can significantly affect its performance and, ultimately, your return on investment. Sauaia recommends considering not only the equipment and components of the solar system, but also the quality of the installation process itself. Asking questions about the quality of the components used and checking certifications and quality control labels can be very helpful. Sauaia also points out that its important to ask about after-sales support and maintenance . Although a solar photovoltaic system requires little maintenance, its important to perform periodic checks to ensure everything is working properly, he explains. Knowing the details of the warranties is also key. Warranties may cover the product, its performance, and installation separately, so if you have any questions, its a good idea to ask the installer to break this information down. Jacopo Piccagali, Project and Policy Officer at SolarPower Europe, adds that homeowners in the European Union have the right to energy sharing. This means you can sell your surplus solar energy to your neighbor or someone nearby. If you cant install solar panels on your own home, you could also buy solar energy from someone nearby, explains Piccagali. This information should be available on the local distribution network operators website. Red flags to avoid when looking for a solar installer Sources consulted by pv magazine recommend that homeowners only purchase from certified and reputable installers . Several experts also warn against choosing an installer based solely on the lowest quote. Ultimately, if a deal seems too good to be true, it probably is. Choosing an installer based solely on price can also mean compromising the quality and safety of the installation. “Quotes far below market rates should be viewed with caution, as they often indicate the use of inferior materials or poor workmanship,” explains Sinethemba Mnguni, Junior Technical Specialist at the South African Solar Photovoltaic Industry Association (SAPVIA). “This can lead to serious problems such as roof leaks or even electrical hazards.” Ahmad Taha, Marketing Director of AG Energies Company Ltd in Tanzania, adds that installers who dont clearly explain their pricing should be considered red flags , as should those who use substandard equipment or promise unrealistic energy savings. Hector de Lama, Technical Director of UNEF Spain, explains that the data sheet for the components to be installed should be shared with the quote . He also points out that the installer should include technical drawings of the installation layout and logistical details . Homeowners should also be wary of pushy sales tactics , as this often indicates something fishy about the offer. “Salespeople who call unannounced or visit door-to-door often offer urgent offers. You shouldnt commit to anything on the spot and should take the time to explore the available options,” warns a spokesperson for MCS Certified UK. “Scammers may pose as legitimate installers. Always check their credentials,” the spokesperson adds. Unfortunately, scams do exist in the solar industry. To avoid them, Bergamasco recommends avoiding installers without a physical address or established market presence, and advises homeowners not to sign any installation agreement without a clear and detailed contract . Several sources emphasize that failing to fully review the terms of the contract is another common mistake . Others warn against using installers who lack the necessary certifications or whose installation procedures dont comply with current legislation in their country. A source in the Chinese residential market adds that failing to verify the installers qualifications is another common problem to avoid. |
