A solar project is nothing without a good inverter - and we only offer the very best. While all inverters perform the same function - to convert sunlight into usable energy - there are some very notable differences between the various types of inverters.
String Inverters (GOOD) - In this case, individual solar panels are wired together into “strings” that send energy to a single inverter that is located within your home. While string inverters are the most affordable, they are also the least productive. These inverters can only perform as well as the lowest-performing panel. For example, if shade or a pile of leaves hinders one panel's performance, every other panel operates at the same diminished capacity. If a few panels fail, the entire solar system may shut down. Warranties average from 10 to 12 years for this type of product.
Optimizers (BETTER) - Optimizers are often used in combination with a string inverter to improve productivity. The benefit of using an optimizer is that it allows you to measure the performance of individual solar panels, which is not possible if you are using a string inverter alone. However, they are more difficult to maintain and will cost a little more. This device connects to a central inverter which creates a single point of failure. This is a good “hybrid” option for anyone who wants to increase the performance of their system without investing in a microinverter. If future upgrades are necessary, additional costs may be incurred. Warranties can range from 10 to 25 years for this type of product, depending on the manufacturer.
Microinverters (BEST) - Microinverters are the most efficient and technologically advanced type of inverter on the market. In the best and worst conditions, a microinverter will produce the most energy. This is because only the individual panel obstructed by shade or covered by dirt will be affected, while the others continue to perform to their fullest potential. This high-tech system also makes it possible to monitor the performance of individual panels and identify the cause of any production issues. Another benefit offered by microinverters is when one inverter goes down, it does not affect the rest of the panels. Understandably, microinverters are the most expensive. This is a good choice for anyone who wants to get the most value out of their solar system or for homes that tend to get a lot of shade. Warranties average 25 years for this type of product.
For these reasons, DIY Solar Power will only offer the best inverters on the market, all of which are microinverters, manufactured by Enphase Energy. Enphase uses the latest technology, highest efficiency, highest product reliability and warranty.
