Types
The installation type sets the commercial structure
Find the type that matches what you hold.
Repowering
Solar repowering
Running the numbers on an ageing plant
How much the same site can carry, though, is set by the permit rather than the hardware.
Separate the loss
We split the drop that degradation explains from the drop that faults, soiling, or shading explain. Different causes, different fix.
Map the permit
We read the existing licence against today's ordinances, and set out what fits inside the 10% band and what the process looks like beyond it.
Price it with the contract
Payback is calculated with the 2027 move to a contract market built in, and with disposal of the old modules costed from the start.
The rules on repowering are still being written. Where something could change, we say so.
Why GRIDAEND
Equipment can be replaced.
The site cannot.
Modules and inverters can be swapped out even after commissioning.
But site conditions, spare grid capacity, and permitting requirements are settled at the very start.
The time spent on the first assessment governs the next 20 years.
Why GRIDAEND
We start from the owner's position
GRIDAEND puts EPC terms together with financing and support programs to design the combination that fits the project owner.
Not a yes or no, but what the site earns under each set of conditions
Energy yield simulation, grid connection, permitting risk, and the 20-year cash flow go into one report. If a site doesn't work, we say so. The assumptions behind the numbers are published with them.
We put the terms side by side
A single proposal gives you nothing to measure it against. GRIDAEND collects competitive bids from several EPC contractors and lays unit price, contract terms, and defect liability warranty out in one comparison table. Financing and government support programs go on top of that, so you can see which combination brings the total project cost down. You make the choice. The point of contact stays the same.
Our scope ends at operations, not at commissioning
A power plant is an asset that runs for more than 20 years. After commissioning we monitor energy yield and settlement records, and keep checking whether ESS or VPP opens another revenue route. The name says it: we start at the grid and stay to the end.

The rules are changing
View all →RPS ends, a contract market begins: what new projects need to prepare
An amendment passed by the National Assembly on 20 August 2026 replaces the Renewable Portfolio Standard (RPS) with a renewable energy contract market. From 2027, new installations no longer receive Renewable Energy Certificates (RECs), and the commissioning date and contract route decide the revenue structure for 20 years.
Roof lease or owner-invested: which one suits your factory
The two rooftop solar structures compared on upfront investment, the form the return takes, who carries which responsibility, and whether the output can count toward RE100. Which one wins depends on how much power you use and how much you can invest.
SMP and REC, plainly: where solar revenue actually comes from
The two halves of solar revenue in Korea, the System Marginal Price and Renewable Energy Certificates, from the definitions through recent prices, and what changes once the market reform lands in 2027.
Revenue
There is more than one revenue structure
We don't promise a fixed rate of return. We publish how the numbers were reached.
Revenue
What you take away
Lease income
You provide the land or the roof, invest nothing, and receive rent for the term of the contract. Operating responsibility sits with the operator.
Power sales
You invest yourself and sell the electricity you generate. Depending on the contract, the price can be fixed for the long term.
Lower electricity bills
Power you generate and use on site never reaches the bill. The more you use, the more you save.
Equity and project returns
On larger sites, an equity structure lets you take a share of the project return on top of the rent.
Added ESS and VPP income
After commissioning, adding storage or joining an aggregated resource opens one more revenue route.
Support programs and financing
We find the government support programs and financing terms the project qualifies for. That brings down the upfront burden and the interest cost.
Actual amounts and rates of return vary with the conditions of the site. The assessment report calculates them for your site.
Channels
We follow the energy market on our channels
Not solar alone: storage and power trading shape a project just as much.
Free assessment
It starts with one line: the site address.
Leave the address and a way to reach you. We send back an initial assessment report within about five business days.
If the site stands up as a project, the report also sets out competitive EPC bids and financing terms.
