RM20,608 in added energy revenue—plus RM20,000 in grass-cost savings per MWp.
SunBooster is an exclusive reflective-membrane technology offered in Malaysia for suitable bifacial solar plants. The base case converts approximately 103 MWh of additional delivered AC energy into added gross income from the same 1 MWp operating asset—without adding another megawatt of modules. With the editable Malaysia vegetation-cost assumption, combined year-one gross benefit reaches RM40,608/MWp.

RM14,000–RM30,800 per MWp, per year
At the same RM0.20/kWh energy value and 1,400-hour assumption, a 5–11% AC uplift corresponds to approximately 70–154 MWh of additional energy per MWp each year. The 8.88% independent proof-of-concept result would equate to about RM24,864 per MWp annually.
Modelled screening results, not a quotation or performance guarantee. The Malaysia 1 MW preset uses approximately RM192,350 installed investment, RM1,200/MWp annual O&M, a 25-year analysis period and 7% discount rate. It also includes an editable RM20,000/MWp/year avoided grass-cutting cost, producing a 4.98-year simple payback and 19.2% standalone membrane-investment IRR. With the grass saving set to zero, the original generation-only case is 11.04 years and 6.6% IRR. Neither figure is the percentage-point increase in the host plant’s total IRR. Results vary with layout, covered area, degradation, clipping, curtailment, contract terms, tax, financing and the existing O&M contract.

Model your MYR returns How it works
Make the rear side work harder.
Bifacial modules can generate from both sides, but ordinary ground absorbs much of the sunlight that passes between the rows. SunBooster changes the ground condition into a productive optical surface.
Model your layout
Capture overlooked irradiance
High-reflectance membrane redirects sunlight that would otherwise be absorbed by soil or vegetation.
Increase rear-side contribution
More reflected light reaches the underside of compatible bifacial modules, lifting DC yield.
Convert uplift into project value
Sellable AC energy, clipping, tariff, maintenance and degradation are modelled over the project life.

Review Malaysia design 
Reflective coverage limits sunlight and growing space beneath the arrayA second return stream for Malaysia
Generate more energy—and spend less fighting tropical grass.
Malaysia’s heat, humidity and rainfall can drive aggressive vegetation growth, including lalang that regrows from deep rhizomes. A reflective membrane also acts as a physical ground barrier across the covered zone, reducing light available to weeds and the area that crews must repeatedly cut.
Malaysia 1 MW model · year oneRM20,608 energy revenue + RM20,000 grass saving = RM40,608 gross benefit
At approximately RM192,350 installed investment, the combined screening case produces a 4.98-year simple payback and 19.2% standalone IRR.
The 10-year horizon reflects the supplied commercial scenario, not a universal life guarantee. Savings apply only to covered zones and should be validated against the site’s mowing frequency, perimeter treatment, drainage corridors, access routes and existing O&M contract. Physical suppression can reduce repeated mowing and spot-herbicide demand; it does not justify claiming that all vegetation management or chemical use disappears across the entire plant.
Capture both value streamsModel energy revenue and avoided vegetation cost together.
Calculate the combined benefit Malaysia preliminary design envelope
Choose coverage around the structure—not from a generic rule.
The supplied quantity workbook supports three common mounting layouts. These dimensions are a pre-design starting point for membrane quantities and fixing counts; final geometry must be reconciled with the actual module, structure, terrain and drainage drawings.

Malaysia project design
Set the geometry from the actual Malaysian site and mounting system.
Approximately 1.5 m tracker-axis height can be screened as an indicative starting point, but row spacing must come from the project layout and energy model. The design team should re-check:
- rear-side view factor and row-to-row shading
- tracker rotation and emergency stow envelope
- design flood level, swales and storm-water flow
- wind uplift, soil pull-out strength and fixing density
- walkways, cabling, access and remaining vegetation zones

LSS6 changes the design conversation
Solar + BESS makes every additional usable kWh more valuable.
PETRA’s LSS6 announcement pairs 2,500 MW of solar with 1,250 MW of BESS across Packages 1 and 2. The separate 150 MW Bumiputera Package 3 is solar-only. For the two hybrid packages, storage is part of the programme architecture—not an optional afterthought.
Why SunBooster + BESS
Capture more sunlight. Store eligible surplus. Dispatch it later.
SunBooster increases rear-side irradiance and potential bifacial output. A properly designed BESS can then capture part of the eligible midday surplus that might otherwise be inverter-clipped or operationally curtailed, and release it during an approved dispatch window.
Membrane redirects unused sunlight toward the module rear side.
Bifacial modules convert the additional rear-side irradiance into DC energy.
BESS charges from eligible surplus within inverter, PCS and state-of-charge limits.
Stored energy is delivered later within PPA, plant-controller and grid requirements.
Design solar and storage togetherQuantify the value of additional usable generation.

Screening model: Added gross revenue = delivered additional AC energy × entered energy tariff. Combined cash benefit also includes the entered avoided grass-cutting cost for membrane-covered zones, then deducts entered annual O&M. NPV and discounted payback use the selected discount rate. Gain = bifaciality × geometry coupling × coverage × (membrane albedo − ground albedo). AC results include a synthetic hourly clipping model. Vegetation savings require project-specific coverage and O&M validation; final design requires simulation, contract review and engineering approval.

Read the technical questions Questions, answered
Understand the system before you specify it.
What is a solar reflective membrane?+
It is a durable, high-reflectance ground surface installed beneath bifacial PV arrays. It redirects more sunlight toward the rear side of the modules, increasing rear-side irradiance and total energy output.
How much additional generation can SunBooster deliver?+
Reference results indicate approximately 5% to 11%, depending on module bifaciality, row geometry, natural albedo, membrane coverage, inverter clipping and site conditions. Every project should be modelled individually.
Can it be installed on an operating solar farm?+
Yes. SunBooster can be evaluated during project design or as a retrofit after commercial operation, subject to access, terrain, drainage and layout checks.
Does the calculator replace PVsyst?+
No. The simulator is an analytical screening and investment tool. Bankable design should be confirmed through project-specific PVsyst modelling, engineering review and, where appropriate, a field pilot.
How is additional revenue calculated?+
Added gross revenue is additional delivered AC energy multiplied by the project’s realised energy value. Net cash then deducts incremental O&M, while NPV and discounted payback apply the selected discount rate. The tariff, clipping and cost assumptions are editable.
Does a 19.2% IRR mean the solar plant IRR increases by 19.2 percentage points?+
No. The 19.2% figure is the standalone IRR of the SunBooster membrane investment when the Malaysia 1 MW preset includes RM20,000/MWp/year of avoided grass-cutting cost. Set that input to zero and the generation-only case is approximately 6.6%. The change in the host plant’s total project or equity IRR requires its original CAPEX, financing, tax and baseline cash flows.
How does this apply to Malaysian power contracts?+
The value of each additional kWh depends on the project’s PPA or supply arrangement, system access charges, curtailment, losses and settlement terms. SunBooster models the physical uplift and commercial assumptions separately so the project team can test the relevant structure.
Can SunBooster reduce grass-cutting cost?+
The reflective membrane forms a physical barrier over the covered ground, limiting sunlight and space available for grass beneath the array. The Malaysia preset includes an editable RM20,000/MWp/year avoided grass-cutting assumption. Actual savings depend on coverage, perimeter growth, drainage corridors, access roads and the site’s existing vegetation-control contract.
What height and spacing should a Malaysian project use?+
There is no universal row pitch or mounting height for Malaysia. The supplied Malaysia workbook models 4.6–5.4 m membrane coverage across common 1P and 2P layouts, but final geometry must be checked against the actual structure, flood level, tracker movement, rear-side view factor, shading, wind uplift, drainage and maintenance access.
What is the stated service life, and what product warranty applies?+
The supplied project analysis uses an effective service-life basis of more than 10 years and describes a 10-year material-level weathering and anti-ageing rating. The CPVT ageing evidence also includes a note equating the tested Oman ultraviolet exposure to 18 years of direct UV or 28 years outdoors when module shading is considered. These are service-life and accelerated-ageing references—not a warranty promise. The warranty period, covered defects, exclusions, remedies and maintenance conditions must be confirmed in the final project technical and supply agreement.
