The geographic location of the construction/renovation?
Square footage of the structure, orientation of structure
(please include in your site sketch a top view drawing of the roof and its divisions -- 3 D helpful but not necessary?
And, does it have a south facing roof (please
indicate on drawing)?
Is the roof shaded or in the sun most of the day (list
approximate hours)?
Approximate pitch of roof (inches per horizontal foot)?
Are there other suitable sunny locations on your lot
for solar?
Describe or sketch them (lot plan very helpful):
Approximate hours of shade (Winter, when the sun if
full, do objects shade the proposed location? Hours of shadows and description of objects causing shade)
Approximate hours of shade at each location? (Summer,
when sun is full, do objects shade the proposed location? Hours of shadows and description of objects causing shade)
Above: We know from solar radiation records the number
of sunshine hours 'per day' averaged over the year in most locations. What we need from you are the total sunshine hours that
are LOST: Sunrise time; (shade hours) caused by trees buildings and other obstructions; sunset time. This will be very
different in summer than in winter so a description of both extremes is very helpful. (You may also try the City of Seattle's
Sun Chart, Memo #417. Information is available at www.cityofseattle.net/dclu/energy their Energy Code website.) Remember that solar radiation (in the northern hemisphere) always comes from the south,
but there are many more hours of solar radiation in the summer. Also, the sun moves northerly as summer approaches and the
day becomes longer and moves southerly as winter approaches and the day shortens. Remember that this is only a preliminary
survery form. Our on-site solar survey employs a "Solar Pathfinder" which accurately displays this solar path. However, if
you are able to approximate the answers to the above questions, it is possible for us to make an estimate.
Please include a sketch of your lot with dimensions.
Also include directions (North) Magnetic or True? (True
North is generally used on most maps and many main roads are laid out on a True North grid)
Sketch open wind paths and obstructions for wind systems.
Use arrows to indicate predominant wind directions.
ENERGY CONSUMPTION INFORMATION:
Please let us know if this is new construction and/or
if you may be willing to change your energy sources for these.
Heating type and energy source?
Cooking type/method?
Clothes drying method?
Hot water energy type and source?
Types of lighting: How many lights, Wattage each, type
and hours of use each day?
Appliances, wattage and hours of use each day?
Is there a well for the structure?
Depth and pump size and voltage --120 or 240 VAC?
Do you wish to consider high efficiency solar or wind water
pumping which can save significant energy?
Topography of the general area (flat, hilly)?
Is the proposed location in a valley or on a hill
or a level area?
DETAILS:
Height and direction of surrounding trees from solar
or wind site? (Indicate which site type)
Buildings that may interfere with sun or wind exposure?
Wind speed details (if considering a wind system, average
wind speed:Average wind speed (see AWEA site)?
Estimates or descriptions of your wind?
Typical seasonal weather conditions (describe).
Do you desire back-up power for essential circuits
only?
Or the whole building?
What are the main objectives you wish to accomplish?
Do you wish to have an independent system?
Or one that feeds the utility when loads are minimum?
Is your interest environmental or economic or both?
Is your utility billed monthly or bi-monthly?
What is your average monthly energy kW (kilowatt-hour)
use?
