1. Traditional Solution2. Lean Solution
• Conventional standard solar modules take about 100 Sq. ft for 1 kW (Consist of walkways)• GI shed replacement happens every 10 years due to corrosion over time (Not a leak proof solution)• Prone to damage during high wind speeds; Not a fire-resistant solution
Traditional or Conventional Solar set up

Solar Integrated Roof- Lean Solution
In simple terms our solution is ROOF + SOLAR integrated in a single product with very important attributes that are not available in traditional solar panels such as
• Protection from Fire – Structure is Fire Resistant• Protection from Wind – Structure can withstand wind speeds upto 200 kmph• Protection from Rain – Structure is a leak proof application• Protection from Weather – Structure has a life of 45-50 years• More Power in same space _ Structure offers min. 30% more installed capacity

Pricing Comparison
• The price of Lean Solution is equivalent to the cost of [Roof + Solar in the Conventional solar system]
• At the same price the client benefits by attributes that aren’t available in conventional solar system such as :
• Leak proof application
• Fire Resistant product
• A product to withstand cyclonic winds
• A product with a life of 45-50 years
Same Price; Better Value
