At Deltool, we make going solar simple and precise. Using your address, the past 12 months of electricity bills, and your cost per kWh, our team will generate a custom OpenSolar design and proposal tailored to your energy needs.
What You’ll Get in Your Proposal
A tailored solar system design based on your roof orientation, location, and energy usage.
System performance estimates showing expected energy generation and savings over time.
Environmental impact benefits, including CO₂ reductions and equivalent offsets (trees planted, km driven avoided, etc.).
Detailed product specifications for panels, inverters, and batteries.
Clear cost breakdown, including equipment, warranties, and payment milestones.
DIY or turnkey options — whether you want to install it yourself or have our accredited installers handle everything.
The proposal will also give you a realistic view of your long-term return on investment, taking into account annual energy price increases.
Our Proposal Fee
A small fee is payable for creating your proposal — but here’s the good news:
This fee will be fully deducted from your purchase with Deltool, whether you choose to buy just the materials for a DIY project or opt for our complete turnkey service.
