Implementing and integrating PV Solar system on a roof, poll or any other structure available to us, must be carried through a chain of events way to determine the site compatibility with the solar system we want to install. That in turn will clear if is possible to achieve that particular energetic target we are aiming at. First step in a good dimensioned system is a proper site assessment.
In performing a site assessment we have to consider couple of parameters. Micro climate variables are of most importance for the future of the system design and integration and for the amount of energy we want to harvest. Those values will proof if our expectations are in any form realistic and can be considered as viable.
Shadings analyse is the most important parameter in a site evaluation.
Typically, designers strive for placing systems in a wide-open, shade-free place and oriented in the time window from 9 a.m. to 3 p.m. towards geographical south, and that in case we are located in the northern hemisphere. Things are becoming more complicated when different obstructive settings are part of our layout or when the solar array is mounted on a roof with stiff pitch. To do a shading site analyse we offer couple of solutions based on devices with a retail value situated at lower tier- couple of hundreds dollars, up to the end tier retail value where shadings and solar irradiance production is mapped for a year round using software, GPS and cameras. Besides evaluating shadings, a power load analyse is determinant and that because we need to find out if the critical load can be covered by our renewable energy system either photo voltaic or wind based. In short our site assessment will be conducted based on shading, wind factor, critical load analyse and site layout dimensional elevations (angle, pitch and distance measurement). Not at very last we will have an array of indirect values to consider, most of the time based on recorded maps and climatic statistics available for that specific geographical microclimate. The indirect factors are those who derate the optimal values of our system trying to match the real working condition.
