Which solar PV system is right for me?

Use this table to help find the right panels for you.  Click on the column heading to sort by that column

Panel manufacturerModel number/reference of the particular panel on test.  Panels from the same manufacturer can vary greatly in performanceCommonly thinking is that mono is better than poly.  At CSP we recognise that there is much more to a panel than just the cell type.  REC as you can see are a very high performing poly cell panel. Perlight and Sharp are poor performing Mono cell panels.Where the company is based.  Hopefully this column will dispell the myth that German Panels are always good and Chinese panels are always bad.Where the production of the panels takes place.  As you can see China produces most of the worlds panels, and there are some great quality panels made in China.  There's more to know about a panel than the country of production.PV Sol is the best level playing field that we have to compare panels.  It takes in to account low light performance, temperature co-efficient, heat capactiyPhoton's test field is in Germany so it's a comparable Northern Europe climate to the UK.  They've field tested many panels over the years.  The debate rages about PV Sol V field testing as Photon will leave snow on the panels and results may be affected by "bird strikes" and other soiling.Effeciency is often used as a major selling point.  If you're not restricted for space on your roof then efficiency is not so critical as it simply refers to the amount of power per square meter as a percentage is turned from light in to electric.This warrranty covers faults due to manufacturing defects.  Some manufacturers give a longer warranty than standard with certain installers.  CSP can offer these warranties.All panels will degrade and these warranties apply to each individual panel.  That is to say if any one panel under performs the levels given then you will have a warranty claim.  However there is suspicion in the market as all degradation could be blamed on build quality, which is normally only covered by the 10-12 year product warranty.Most warranties will either give you a refund of the cost of a panel or send you a replacement.  You will normally have to meet the installation costs. Sunpower are the only manufacturer that offers a complete cost of replacement warranty.Some manufacturers have obtained independent degradation simulation testing.  In reality most standard cells are going to lose about 15% in power over 25 years, except Sunpower's maxeon technology.Solar panel manufacturers websiteCSP have seen some big brands come and go.  BP used to make great panels, then they pulled out of the market.  We've generally seen better panels, with more focus on improvement from companies that are commited to solar rather than a big brand who leverage their brand as a selling point rather than making good panels as they don't have any commitment to the Solar PV industry.Company finances can be hard to establish.  These figures are taken from 2013
