Wind and Solar Site Survey
Onsite Wind and Solar Site Surveys are scheduled over a 10 day period. These are confirmed by email or telephone as to designated date and time. Time is given in a range of several hours.
Wind Turbine sitting will consider the risk of interference with the surounding and will investigate local ordinances regulating the deployment.
It is not necessary for the client to be onsite for the Survey Data Collection Phase but the client should be aware that the service provider may scale the roof to take appropriate measurements. Data Collection takes about one hour for residential surveys and longer for buildings, particularly with significant roof obstructions (A/C, vents, piping, etc). It is important for the client to pre-determine that there is a southerly or east/west solar exposure that is not shaded by trees or other nearby obstructions. Solar arrays are not practical on north facing roof surfaces.
Relevant data is collected regarding surface dimensions, degrees pitch, true azimuth readings, roof assessment, meter(s) location, partial shading and other factors which will determine the potential for solar array placement and where. A client should indicate in advance to the Wind Solar Pro representative if 'ground mount' structures are viable. Usually ground mounts require large open areas; they are often not applicable to residential lots. If the residence is over 40 years old, the client should check or have the Wind Solar Pro technician examine the electric distribution panel, usually in residential garages or basements, to insure there is one available 30 amp circuit breaker or space for one, for system connectivity. Likewise, for such older structures, a check should be made of roof rafter structure, noting rafter size ( e.g. 2X6 or 2x8) and approximate distance between rafters.
Data Analysis and Presentation
The data are analyzed and presented showing the applicable dimensioned roof sections for solar. This information can be used to directly source bids from numerous solar installation contractors. In addition, a pro forma solar installation design and financial estimate is provided to give the client a benchmark against which installation vendor proposals can compared.
