Overview

Many companies want clean energy but prefer not to tie up capital or take on system operation. Du Long Power's investment model solves this: we invest, build, operate and maintain; you receive the benefits of the model you choose.

Scope of service

  • Free assessment of your roof and electricity demand
  • 100% investment in equipment and installation
  • Handling of required procedures
  • Operation, monitoring, cleaning and maintenance of the system
  • Handling all technical issues throughout the contract term

Two partnership models

01

Factory roof lease

Du Long Power leases your factory roof to install a solar system and pays you rent on a regular basis. At the same time, the roof is shaded, cooled and protected.

  • No investment, plus a stable additional income from roof rent
  • Competitive roof rent, agreed based on roof area and actual conditions
  • Rent paid on a regular schedule set out in the contract
  • Long-term partnership with a flexible contract term
  • Du Long Power bears all investment, operation and maintenance costs
02

Shared-savings partnership (ESCO)

You use electricity from the solar system at a price lower than grid electricity. During the contract term, if you wish, you can take over (buy back) the system under mutually agreed terms.

  • No investment; lower electricity costs from the first month of operation
  • Solar power priced below the grid tariff, with the discount stated in the contract
  • Pay only for the solar energy you actually use
  • Long-term partnership with a flexible contract term
  • Option to buy back the system during the contract term if needed, under mutually agreed terms
