Thanks for choosing FOSS as your solar energy supplier; next we mention the scope of the solar evaluation at your facilities.

  1. Solar Azimuth and elevation analysis.
  2. Optimum location and irradiance analysis.
  3. (Solar Peak Window) analysis
  4. TS (True South)
  5. Evaluation of installed capacity/systems
  6. System efficency calculation
  7. Pre-design of system.
  8. Estimate of system installation.

The cost of the evaluation has to be paid in full so to program the visit.

(Our good engineering practices: if after the analysis the site has less tan de 65% of usable sun we will refund 35% of the initial charge, since a site with such characteristics is not good for solar systems).

  • Contractors please call for an estimate if 10 houses or more.
  • We use state of the art software and equipment for this service and we will supply a full dossier upon completion.
  • If you choose to install the system, we would require 60% down payment and the balance upon completion of system install. The cost of the solar evaluation would be then taken into account of the full price.
