Project preparation
Solar Power Plant Project Report: DPR Inputs and Checklist
Prepare the evidence for a solar power plant DPR: AC/DC capacity, land, generation, offtake, grid connection, costs and funding, with a free input checklist.
Start by defining the solar project
A solar power plant project report should explain the proposed generation system, its site and delivery plan, how electricity will be used or sold, and how those assumptions translate into costs and cash flows. A credible report needs project-specific evidence behind each connection.
Record whether the proposal is ground-mounted or rooftop, grid-connected or another arrangement, and whether the commercial model involves sale to a buyer, captive consumption or another defined use. State both MW AC and MWp DC where applicable: the export/inverter capacity and module capacity are not interchangeable.
This guide concerns electricity generation. Solar-cell manufacturing needs a different process, utility and supply-chain assessment; see the manufacturing input checklist.
What a solar power plant DPR should substantiate
| Workstream | Evidence to assemble | Usual input owner |
|---|---|---|
| Project and promoter | Company, ownership, relevant experience, proposed capacity, location and development stage. | Promoter / finance team |
| Land and site | Title or lease records, access, site layout, terrain information and approval status; roof condition and rights for rooftop projects. | Developer / land and technical teams |
| Technical configuration | Module and inverter specifications, AC/DC sizing, layout, electrical arrangement and major scope boundaries. | Designer / EPC contractor |
| Generation assessment | Resource data, model version, loss assumptions and the basis of monthly and annual energy estimates. | Energy assessor / designer |
| Grid and evacuation | Connection correspondence, receiving point, evacuation scope, responsible parties, cost and completion dependencies. | Developer / relevant network utility |
| Offtake or consumption | PPA terms and status where relevant; consumption records and the commercial basis of any proposed savings. | Commercial / consumer team |
| Delivery and operations | EPC scope, procurement milestones, commissioning plan, warranties and O&M responsibilities. | EPC / O&M teams |
| Cost and funding | Dated estimates, exclusions, incurred expenditure, equity plan, borrowing assumptions and model schedules. | Finance / project teams |
Track approvals as obtained, applied for or still to be initiated. Identify the relevant authority and due date for the specific state, site and commercial structure. A Karnataka utility reference in an earlier checklist is not a national requirement.
Connect the generation study to the revenue model
The report should make clear how the energy forecast was produced: weather/resource inputs, equipment assumptions, shading, temperature, electrical losses, availability and degradation treatment. Explain what is included in the energy figure and where it is measured.
Keep gross generation, net export, billed energy and collected revenue distinguishable. For example, a forecast at the inverter output should not silently become electricity delivered at a different settlement point. Use a consistent loss and charge treatment through the model.
For a sale project, document the buyer, tariff basis, term, payment arrangements and agreement status. For a consumption-led project, use relevant demand and billing records, then examine how the proposed generation aligns with consumption. Applicable charges, settlement rules and approvals need project-specific confirmation.
A useful consistency check
If the generation forecast changes, trace the effect into monthly revenue, operating cash and repayment coverage. If grid readiness moves, update the commissioning schedule and construction cash requirements as well. Changing one summary cell is not a revised DPR.
Preparing a 1 MW or 5 MW solar project report
Capacity alone does not determine a complete report. A 5 MW proposal is not automatically five copies of a 1 MW financial model. First clarify whether the stated capacity is AC or DC, then obtain the site and connection evidence for that design.
| Question | What to establish for either capacity |
|---|---|
| Site and layout | Use the actual topography, access, shading and equipment arrangement; do not multiply a generic land allowance. |
| Grid interface | Confirm the receiving point, connection arrangement, evacuation works and responsibilities with the relevant parties. |
| Cost estimate | Price the chosen system and scope. Shared infrastructure, civil works, contracting and equipment choices may change unit costs. |
| Operating case | Use the project’s generation assessment, O&M offer, insurance and replacement assumptions. |
| Financing | Model the actual proposed drawdowns and repayment terms, with commissioning and revenue timing aligned. |
The checklist below works as an input-collection aid for either capacity. It is not a completed 1 MW or 5 MW solar power plant project report.
Review costs, funding and downside cases together
Reconcile land or lease costs, site development, plant equipment, civil and electrical works, evacuation, pre-operating expenses and other items within the agreed scope. Distinguish quoted prices from allowances, and show inclusions, exclusions, taxes and the estimate date.
Match the funding plan to the expenditure schedule. State how additional costs or delayed revenue would be funded instead of assuming that a contingency line or an uncommitted facility will cover every gap.
- Lower energy delivery: show the effect on revenue and period-by-period debt coverage.
- Delayed commissioning: move the revenue start date and examine the associated construction-period costs.
- Higher capital or operating cost: identify the revised funding need and cash-flow effect.
- Collection or settlement changes: examine working cash requirements using the relevant commercial terms.
Choose plausible scenarios with the technical and finance teams. These are review questions, not forecasts or recommended return thresholds.
Download the solar project input checklist
Use Bitcon’s printable preparation checklist to assemble documents and assign owners before the DPR or TEV appointment. It is adapted from our solar-project working checklist, with historical cut-off dates replaced by the agreed assessment date.
What this download contains: input requests and review prompts. It is not a feasibility conclusion, design certification or completed solar DPR. Project assumptions, technical findings and current requirements must be checked for the actual appointment.
For institutional application forms, consult the intended lender. IREDA’s official forms and checklists provide a reference for applications to IREDA; confirm the current project-specific list with its team.
Solar engineering experience behind the questions
Bitcon’s documented assignments include owner’s engineer / PMC work for the 22 MW AC / 28 MWp DC Rampura project, commissioned in April 2022, and design and detailed engineering for a 4.80 MW AC / 6.72 MWp DC project. Their stated roles are engineering and project support; they are not presented as solar-generation DPR assignments.
For report preparation, explore Bitcon’s DPR service. If the bank instead requires independent appraisal, review the TEV appointment scope.
Solar report questions
Can a generic solar report PDF be submitted for funding?
It can illustrate a structure, but the lender needs evidence about the actual project, promoter, site, technology, offtake, costs and proposed financing. Confirm its required scope and consultant appointment.
Can I use one per-MW cost for every site?
A benchmark can help screen an early idea. A DPR needs a project-specific estimate with dated quotations and clear scope, including infrastructure and costs outside the main EPC package.
Is the checklist a list of every statutory approval?
No. It helps collect information. The applicable permissions and current technical requirements depend on the location, configuration and commercial model; confirm them with the relevant authorities and specialists.
