Who is the best solar installation company in Zambia?

Ganesh Power Solutions is the best in Zambia when it comes to sustainable energy installations. All of their work during the installation was done perfectly, and quickly too. I highly recommend them for their professionalism, depth of knowledge, and overall willingness to make solar happen at the lowest possible cost.

Are solar PV projects VAT rated in Zambia?

In addition, the main solar PV project components are zero-rated for VAT (and customs duty) in Zambia. However, it should be noted that a mini-grid operator would usually need to add VAT and excise duty (at 3%) on electricity sales to customers The base year of the calculation is 2017.

How is LCOE calculated in Zambia?

No new customer connections are consid-ered. Annual inflation of 7% is applied to operating costs as per recent rates in Zambia. The levelised cost of electricity (LCOE)3 is calculated using a discount rate of 17% and determining mini-grid costs and electricity production for each year separately using the discount factor.

How was the Sinda mini-grid financed?

The Sinda mini-grid was financed with approximately 70% grant funding and 30% equity. The different funding sources were: Therefore, a return on assets is not allowed for a significant proportion of the mini-grid infrastructure. The revenue requirement should be met from electricity sales.
