Tips on Purchasing a Good Solar System
Buying a home solar power system can be a very exciting experience but the client should not get carried away by the advertising but they must focus on the vital
aspects of the purchase because it is a huge investment and one that will be there for a long time to come thus it is critical to choose wisely. It is good to get references from family, friends, colleagues and neighbors that have solar systems installed because they will be able to tell the potential buyer about their experience and alert them of any problems that they may have experienced so that the consumer can avoid certain companies. Most solar installers offer a warranty on their products thus it is important to consider the length of the warranty that the solar company offers and if the manufacturer is reliable then the warranty on the solar panels has to be substantial thus it should not be less than 25 years because they would naturally expect the solar panel to last longer than that and long enough for it to pay for itself and make a decent profit.
It is good to state that the client needs to have realistic expectations because if they are paying very low for the same size of systems then the system may have of poor quality and have poor installation work because in most cases quality equipment and sound installation is not cheap just like on all other purchases and the customer normally gets their money’s worth.
A known fact is that solar panels need certifications right from purchases especially for purchases that could attract a government rebate and the certification on the solar panel indicates the type of testing that has been done on them such as the TUV IEC 61215 shows that the solar panels have been tested by an independent lab and have met the specifications advertised on it. The client also needs to decide on the types of panels that they need because a while back its used to be a common practice that if the person had a limited roof space they would need highly efficient and very expensive mono-crystalline panels but this has recently changed with technological advances in polycrystalline panel technology and other film technologies. Even if the client has enough roof space they would want to consider panel sizes versus output because filling up the roof with inefficient panels will affect the ability to add more panels later and it also does not maximize the power output of the space but it is good to note that regardless of what a company claims no solar panel technology will produce any significant amount of power in full shade.Roofs – Getting Started & Next Steps
