I will design professional solar pv 3d models and layouts in sketchup

1) The project's GPS coordinates (latitude & longitude) 2) Your estimated total energy demand (in kWh) 3) Any site drawings or sketches with measurements 4) Preferred equipment datasheets (for solar panels, inverters, batteries, etc.), if you have any

Yes, absolutely. Upon order confirmation, I will send you a simple guide and template to list your appliances and their usage. I can then calculate your total PV system demand (in kWh) to size your system correctly.

Yes, I have experience designing systems for a variety of roof types and challenging sites (including flat roofs, shaded areas, and irregular shapes).

While not always mandatory, a handmade drawing of your project site with clear measurements (roof/land dimensions, shading objects, etc.) is extremely valuable. It allows me to provide a more precise panel layout and system design, avoiding potential issues during installation.

I offer revision packages to fine-tune the design based on your feedback. This ensures the final plan perfectly matches your expectations and any new site constraints that may arise.

Your exact latitude and longitude are crucial for calculating solar irradiance (sunlight intensity) at your location. This allows me to accurately simulate your system's energy production across different seasons, ensuring your design is optimized for maximum efficiency.
