Answer
No single verified price forecast applies to every 2026–2028 solar purchase. Module prices depend on specification, delivery market, contract terms and policy exposure. Use dated benchmarks to understand market direction, then compare current supplier quotes on the same delivery basis. Model plausible price changes as project scenarios rather than treating an unsupported global forecast as a procurement commitment.
What the available price evidence actually says
A useful forecast identifies the market, equipment, observation date and delivery basis. A worldwide price per watt without those details cannot establish what an installer or developer will pay for a particular order.
The Department of Energy’s Quarterly Solar Industry Update summarizes the Fall 2025 report, published November 19, 2025. It reports global module pricing around USD 0.09/Wdc and US module prices around USD 0.27/Wdc in Q3 2025. These are historical market observations, not September 2026 supplier quotations or forecasts for 2028. They also concern modules, not a complete installed system.
For a more recent forecast source, Intertek CEA’s report catalogue lists a Q2 2026 PV Price Forecasting Report dated August 27, 2026. The publisher describes regional forecasts and cost components including materials, logistics and foreign exchange. The full forecast was not retrieved for this review, so this guide does not assign numerical 2027–2028 prices or reproduce an analyst quotation from it.
Anza’s pricing information page describes segmented supplier-pricing and availability data. Its public page does not establish a current transaction price for your project. Obtain the relevant dated dataset or a written supplier quotation before using a price in a purchasing commitment.
Compare quotes on the same basis
Two offers with the same USD/Wdc can represent different delivered costs. First confirm that the quoted wattage is the module’s rated DC capacity and that the price applies to the same quantity and delivery schedule.
| Quote field | What to record | Why it changes the comparison |
|---|---|---|
| Equipment | Manufacturer, exact model, rated power and revision | A technology label alone does not identify the product |
| Quantity | Module count, total rated capacity and minimum order | Small and large orders may have different terms |
| Delivery | Named location, date and Incoterm | Freight, insurance and responsibility can differ |
| Origin | Relevant manufacturing and traceability documents | Policy exposure may depend on the supply chain |
| Currency | Currency, exchange assumption and payment dates | Exchange movements can affect project cost |
| Taxes and duties | Included, excluded and contractually allocated amounts | An advertised module price may omit landed costs |
| Commercial terms | Quote expiry, deposit, milestones and cancellation terms | A lower price can carry different cash-flow risks |
| Quality and warranty | Datasheets, certifications, warranty issuer and remedies | Procurement needs an acceptable product, not only a low price |
Keep the original quotation alongside the comparison sheet. If a supplier offers a substitute model, rerun the equipment and layout checks rather than assuming equal nameplate power means an interchangeable design. The module-selection guide explains design considerations for bifacial equipment; the project team must still verify the specific product.
Build a 2026–2028 scenario without inventing a market forecast
Start with a dated, project-specific quote. Record its expiry and expected delivery date. Then create alternative prices that answer a planning question: how much cost movement can the project absorb before its budget or financial case changes materially?
For an illustrative 5 MWdc order, a hypothetical module-price change of USD 0.02/Wdc changes module expenditure by:
5,000,000 Wdc × USD 0.02/Wdc = USD 100,000.
That is arithmetic for a stated scenario, not a prediction that prices will move by two cents. It excludes changes in freight, duties, finance, equipment quantity and other project costs.
Use a table with buyer-supplied assumptions:
| Scenario | Input to supply | What to review |
|---|---|---|
| Current quote | Documented price, expiry and delivery terms | Is it executable for the intended order? |
| Higher-price case | Explicit price increase chosen for sensitivity analysis | Is contingency sufficient? |
| Lower-price case | Explicit price decrease chosen for sensitivity analysis | Would waiting create a schedule or availability risk? |
| Delayed-delivery case | Revised shipment and commissioning dates | What contractual and financing consequences follow? |
Keep price changes separate from changes in energy yield, tariffs and financing. Otherwise a favorable financial result can hide which assumption produced it. For the distinction between equipment price and lifetime energy cost, see solar LCOE by country.
Why regional prices and tariff exposure differ
A factory-origin benchmark and a delivered-market price describe different transactions. Freight, distribution, financing, warranty arrangements and applicable trade measures can all affect the gap. A ratio between two market averages does not identify a universal tariff percentage.
Before signing an import contract, have the responsible customs or trade adviser verify the current rules for the product classification, exporter, origin, destination and entry date. Ask how a rule change is allocated under the contract. Avoid adding several headline percentages without checking their assessment bases and interaction.
For 2027 or 2028 procurement, treat a present rule as a dated assumption that needs another review before shipment. A supplier’s marketing statement does not replace the relevant official determination or project-specific advice.
Decide when to lock a price using project constraints
There is no universal instruction to buy now or wait. Compare the quote’s validity with design freeze, equipment approval, construction milestones and the required delivery window. Confirm that the order matches the approved design and that storage or early-delivery costs are included if commissioning is later.
Record who owns each risk: module substitution, late delivery, exchange movement, policy change and warranty enforcement. A procurement decision becomes reviewable when the team can see the accepted risks and the evidence used to price them.
If you are evaluating SurgePV’s solar design workflow, bring the shortlisted module specifications and project constraints to the evaluation. Ask how the selected equipment fits the design and which outputs are available for your workflow; do not assume a design platform supplies live procurement prices.
Frequently asked questions
What is the solar module price forecast for 2026–2028?
A defensible forecast must specify the region, equipment, delivery basis and assumptions. This guide provides dated evidence and a procurement scenario method; it does not present an unverified global price curve as a confirmed forecast.
Does a low module price mean a low installed solar price?
No. A module quotation is one cost input. Equipment beyond the modules, installation, freight, applicable duties, financing and other project requirements can affect the final installed cost.
Should developers lock prices now or wait?
Compare a valid supplier quote with the project’s delivery deadlines, design approval, budget contingency and contract risks. The appropriate choice depends on those constraints; a general market headline cannot decide it for every project.
