The price and advantages of solar pv system

Just with any product, the age old saying “you get what you pay for” is relevant to energy systems. Let’s slice a PV system to better understand the cost difference. Whether you lease or purchase a solar system  you may find yourself asking, “Why does this system cost more than that system?” “Is this installer overpriced?” It could be a matter of installation price, but more than likely the cost difference is in the components.

Now,lets see the advantages of the solar pv systems:

Solar Modules were compared at the Photon Laboratory in Germany. The benchmark for the yield measurement is based on the number of kilowatt-hours produced by the front side of a module. Not all panels are equally capable of collecting the same amount of energy.

While the performance ratio is the decisive criterion for the technical quality of a solar module, technology alone is not the only measurement. Long-term stability is equally significant for a product that needs to function well for at least 20 years. Panels that offer durability come with longer warranties.

Proper racking provides a support for modules to ensure proper installation. A good racking system aligns solar modules evenly; creating a flush, clean line. Flashings for roof penetrations and wire management are extremely important for long lasting, worry free performance of PV systems Inverters. 

Micro-inverters attach to each solar panel and therefor make array expansion easy. Inverters that convert power for an entire array limit expansion of the system. Optimizers can be added to these string inverters to allow for more flexibility  Also when micro inverters or optimizers convert power individually, shading on one panel won’t affect the output of the other panels. Micro inverters or optimizers allow you to get the most power from your system.

Some systems have the capability to be monitored on-line. You can see exactly how much power your system is producing as well as identify any modules that may be under producing. If you are leasing a system you might find it interesting to know exactly how much power the system is actually providing and if the lease makes sense.
