Sunrise Prima was established in 2023 to support Malaysia’s growing renewable energy sector with solar mounting structures.
Through a strategic collaboration with Solar Sentinel, Sunrise Prima combines structural engineering expertise with solar system design, supporting efficient and dependable solar mounting solutions.
Discuss a solar projectFor the complete solar PV system, Sunrise Prima works in strategic collaboration with Solar Sentinel Sdn Bhd, which is also based in Telok Panglima Garang, Selangor.
Solar Sentinel’s services cover consultancy, design, supply, installation, and testing and commissioning of complete solar PV systems, including turnkey projects.

The presentation includes illustrative operating models and calculations. Project sizing, commercial terms and savings need a site-specific assessment.
1 / 13 — Power your site
A text guide to the “Power Your Site” presentation.
The January 2026 presentation uses illustrative models and calculations. Confirm system design, applicable tariffs, commercial terms and approvals for your own site.
The presentation discusses reducing reliance on diesel generators and grid electricity, managing recurring energy costs, and limiting noise, emissions and downtime. Predictable energy costs and convenient deployment are intended benefits, rather than measured results for a named project.
Model A connects solar PV panels, battery storage and an inverter to construction-site loads. Solar supplies daily operations while the battery stores excess energy for night-time and low-sun periods.
The presentation positions this model for long-duration or remote construction projects, with the aim of reducing grid and diesel reliance, noise, emissions and fuel logistics.
Model B uses solar to offset daytime demand, with battery discharge during high-load periods to cap maximum demand. The presentation assumes weekday peak hours of 2pm–10pm.
The model is presented for grid-connected sites with high peak usage. Changes in capacity or network charges, genset runtime and fuel use depend on the site and its applicable tariff.
The source identifies night-time operations, site location, equipment use, offices and workers’ quarters, cleaning and concrete-related activities as electricity-use drivers. Its chart uses indicative relative impact rather than metered consumption, and attributes its normalised scores to Esmaeilifar et al. (2015).
Slide 6 assumes a medium-sized construction site with 100–200 workers. This is a worked example, not a standard system specification.
| Equipment or use | Power | Daily use | Daily energy |
|---|---|---|---|
| Site office: lights, computers and AC | 5 kW | 12 hours | 60 kWh |
| Worker quarters: lights, fans and small appliances | 10 kW | 12 hours | 120 kWh |
| Portable tools and small machinery | 10 kW | 6 hours | 60 kWh |
| Water pump and cleaning | 5 kW | 6 hours | 30 kWh |
| Security lighting | 2 kW | 12 hours | 24 kWh |
| Total estimated daily energy | 294 kWh/day | ||
The presentation rounds this example up to approximately 300–350 kWh/day for safety and future expansion.
Slide 7 uses about 4–5 peak sun hours per day in Malaysia and allows approximately 20% system losses from the inverter, wiring, dust and other factors. Its formula divides daily energy by peak sun hours multiplied by efficiency.
350 kWh/day ÷ (4.5 hours/day × 0.8) ≈ 97.2 kW
The presentation rounds this to a 100 kW solar PV example. Its illustration labels a 330 Wp module measuring 1.0 m × 1.7 m and an array footprint of 27.2 m × 19 m. These are illustrative dimensions, not a project layout.
Slide 8 assumes two days of autonomy: 350 kWh/day × 2 days = 700 kWh. It separately discusses lithium-ion batteries at 90% depth of discharge and lead-acid batteries at 50%, with an approximately 1,400 kWh lead-acid example.
The source does not clearly distinguish usable from nominal capacity in its lithium-ion example. Confirm battery capacity, depth of discharge and reserve requirements with the project designer before sizing a system. The illustrated battery container is labelled 6.05 m × 2.43 m × 2.89 m.
| Buy | Lease |
|---|---|
| Asset ownership | Project-based pricing |
| Positioned for long-term cost savings | Positioned for lower upfront cost |
| Suited to repeated use across sites | Suited to short or one-off projects |
Ask the team which options are available and request pricing and terms for your project.
The presentation describes local support, practical site advice, one coordination point, configurations to match the bill of quantities, documentation for architects and consultants, and multiple brands. It discusses temporary and mobile sites, relocation between projects, and plug-and-play deployment.
Intended benefits include more predictable energy costs, stable power for equipment and offices, sustainability information to support tenders and approvals, and reduced noise and emissions. These are the presentation’s aims, not guaranteed tender outcomes or project performance.
The presentation says performance depends on panel orientation, shading, dust, peak loads such as welding machines and high-power tools, seasonal variation and rainy days. It discusses a hybrid system with a small diesel or genset backup as an option for construction sites.
The setup slide covers site preparation, installation and commissioning, approval considerations and power availability aligned with the construction programme. It does not establish a quantified installation duration. Confirm preparation, approvals, delivery and commissioning requirements with the team.

Discuss your siteSunrise Prima Sdn Bhd provides engineered solar mounting structures designed to support reliable and efficient solar PV installations. It was established in 2023 as the group’s solar arm to support Malaysia’s renewable energy sector, and works through a strategic collaboration with Solar Sentinel, which brings solar system design alongside the group’s structural engineering expertise.
In the “Power Your Site” presentation on this page, Model A, a self-sustaining site, uses PV panels, an inverter and batteries to run construction loads, including at night and in low sun, and suits long or remote projects. Model B, peak shaving, offsets daytime demand and discharges batteries during high-load periods, and suits grid-connected sites with high peaks.
No. The presentation’s numbers, such as a medium site using about 300 to 350 kWh a day and a system of roughly 100 kW at 4.5 peak sun hours, are worked examples. Orientation, shading, dust, peak equipment loads and rainy seasons all change real performance, so every system needs a site-specific assessment before sizing, pricing or savings are discussed.
The presentation describes two routes. Buying suits owners who want the asset and will reuse it across sites. Leasing suits short or one-off projects where a lower upfront cost matters. Availability, pricing and terms for either route are confirmed with the team for each project, so contact Ducero with your site details.
