The size of your solar PV system will depend on:
• what portion of your electrical consumption you wish to generate
• the physical unshaded area available for the installation of your panels
• how much you are prepared to spend
This is the first step to take when determining if solar is a viable investment. The first step in this regards is to do the load analysis of your facility. Due to net metering facility the most benefits will be only available based on the self consumption. In case you are injecting surplus energy after the billing cycle, it will be purchased by the utility at a price lower than the grid electricity price. Hence it is important to assess the consumption of your facility.
