Each homeowner’s site is unique in many ways. Solar PV systems provide a mini-power plant that will produce electricity for years to come and require good planning and execution.
While doing customer site analysis it is very important to consider many aspects such as,
A customer’s postcode or equivalent provides solar consultants with a starting point to cite typical sunshine hours at a given location due to latitude and climate.
Your solar consultants need to advise your customers thoroughly.
A common calculation made by solar consultants and customers determines system size of a solar PV array. This calculation of system size must consider varying output levels due to:
The sunshine hours of the geographical location are an important factor in determining the efficiency of the solar system. For example Australia’s Solar Zone 4 is expected to have 3.7 hours of sunshine per day. A standard 1KW rated PV array in Zone 4 may produce 3.7 KWhrs of power subject to panel and inverter assumptions.
CEC Handbook lists the output efficiencies for standard PV systems at various Azimuth Angle and Roof Pitch. For example Panels mounted on roofs at 30 degrees pitch and facing True North will produce at 100% output efficiency due to highest irradiation at that orientation. A standard 1KW system at such orientation will produce 3.7 KWHrs in Solar Zone 4.
Panels and inverters have specific conversion efficiencies. Panels produce less power at temperatures higher than STC (Standard Test Conditions) temperature. Inverters operate at varying conversion efficiencies (from DC to AC) and at various voltages from PV array.
Solar eCRM has tools integrated from Google Maps for Sales Reps to look at roof area and sketch out the possible panel positioning in different sections.
Solar eCRM uses the data provided by Clean Energy Council of Australia to estimate the power output at varying Azimuth Angle and Roof Pitch.
Solar eCRM uses the postcode of the customer’s solar site to automatically select the appropriate Solar Zones (defined by Australia’s Clean Energy Council).
This eliminates potential errors in rebate calculations, in pricing and also errors in savings and payback period estimates.
Solar PV System Selection starts with:
Solar eCRM function allows selection from range of products set-up by the Administrator.
It also protects Sales Reps and the company from potential issues arising out of customers expectations on power output and savings and makes the process of quoting a breeze.
