Design – Solar PV systems can be built catering to different needs. Here are a few commonly available options –
Grid-Tied Systems where the house is connected to the main power network or the national grid.
Off-Grid Solar PV Systems are self contained systems that store power in batteries and release it when Solar PV Panels are not producing enough power.
A Hybrid Solar PV System is connected to the grid for exporting power as well as batteries to handle power cuts and store power for local use.
Batteryless Solar photovoltaic systems – This is where the generated energy is supplied to the appliances directly .
Choose the one that meets your needs.
Installation – Solar PV systems consist of the following components –
PV Array : collection of PV modules or PV Cells that convert sunlight to electricity.
Mounting and wiring Systems : systems or components needed to integrate solar modules into the physical and electrical design of the home
System monitors or meters : display devices showing the system performance.
Off and On Grid Inverters : battery or non-battery backed to export and store energy for reuse. Auxiliary fittings : additional fittings such as surplus power diversion manager for enhanced performance.
Location – This is a major factor that affects the performance of any solar PV system.
Choose a system that goes with the structural design of your house.
Select a location(many people prefer south) on your roof-top where there is no or less shade during the day time.
Get the system installed in accordance with the orientation of your house and the angle of sunlight from there to get maximum output.
Make a brief study about the weather conditions of your location and inform your PV dealer about it.
Financial and quality Considerations –
Make a survey about the cost of PV systems available from different dealers.
Study about their quality and make; if needed take the advice or help of your most trusted electrician or engineer.
As much as possible gather information about company reputation, warranties, terms and conditions of sale, performance of the product and service efficiency.
Finally choose the one that fits into your budget and meets most of your expectations while performing.
