150kW Solar PV Energy Storage System: Commercial & Industrial Solar + Storage

The 150kW solar PV energy storage system is an integrated solar-plus-storage solution built for commercial and industrial projects — factories, farms, warehouses, hotels, schools, supermarkets, cold storage and commercial buildings. During the day, the system generates solar power to run your equipment directly and cut what you buy from the grid; surplus energy is stored in the battery and released at night, during peak hours, or when the grid goes down. Paired with a 288kWh battery, the system both lowers your long-term electricity costs and keeps critical loads running when the grid is unstable.

One thing to clarify up front: the 150kW in the name refers to the rated output of the inverter/PCS, not the total wattage of the solar panels. The number of panels is customizable to your project — for example, with 600W panels, 240 panels give you about 144kW of PV capacity. If your project needs more PV, the panel count can be increased to suit the design.

What's included in the system?

A complete 150kW solar-plus-storage system usually consists of:

Which projects is it suitable for?

A 150kW rating plus 288kWh of storage covers most small-to-mid commercial and industrial loads. Here's how it helps by sector:

Factories　Suited to small and mid-size factories and workshops — lighting, fans, air compressors, packaging equipment, control systems, office equipment and part of the production line. Factories with long daytime operating hours benefit most from cutting grid usage with solar.

Warehouses　Warehouse roofs usually offer large surface area, ideal for panels. The system can power warehouse lighting, ventilation, monitoring, office areas and some charging equipment.

Farms　Suited to farms, livestock operations, irrigation and agricultural processing — water pumps, irrigation systems, ventilation, refrigeration, livestock equipment and lighting.

Hotels　Suited to hotels, resorts and guesthouses — common-area lighting, water pumps, kitchen equipment, laundry, networking, monitoring and part of the air-conditioning load.

Cold storage　Suited to food storage, cold-chain and cold-room projects — part of the refrigeration load, lighting, control and monitoring systems. For cold storage, pay close attention to compressor power, startup current and required backup time.

Schools　Suited to schools, training centers and public buildings. School daytime usage aligns well with solar generation — classroom lighting, office power, computers, projectors, networking, fans and part of the AC load.

Supermarkets　Suited to supermarkets and convenience stores — lighting, refrigerated cabinets, POS systems, monitoring, ventilation and office equipment.

Commercial buildings　Suited to office buildings, commercial centers and public buildings — lowers common-area and office energy costs while supporting lighting, office equipment, networking, security, ventilation and part of the AC load.

What equipment can the 150kW system run?

How much it can run depends on equipment power, run time, battery level, solar generation and system design. Common references:

Important note: for water pumps, air compressors, refrigeration compressors, AC units and production equipment, don't look at rated power alone — also account for startup current and the number of devices running at the same time. These two factors often determine whether the system can drive the load reliably.

How long does the 288kWh battery last?

288kWh is how much energy the battery can store. The larger the load, the shorter the runtime; the smaller the load, the longer it lasts. Estimated backup time by load:

These are estimates. Actual runtime is affected by system efficiency, reserved battery capacity, ambient temperature, battery aging and load variation. For longer backup, power only critical equipment — lighting, monitoring, networking, water pumps, control systems or part of the refrigeration load.

Can it keep running during a power outage?

Yes — but backup functionality has to be designed in from the start. A standard grid-tied system won't necessarily keep supplying power when the grid goes down.

If you want the system to keep working during an outage, first decide which equipment must stay on (lighting, monitoring, networking, water pumps, cold storage, POS or control systems), then size the battery and distribution around the total power of those loads and the backup time you need. A few questions to settle before design:

How much power does it generate per day?

Daily generation depends on the project's country and city, sunlight conditions, panel count, tilt, shading, weather and system design. Because this system is named after its 150kW inverter output, actual generation also depends on the panel configuration — which is exactly why tools like NREL's PVWatts estimate output from a project's specific location and conditions rather than quoting a fixed daily figure.

A quick rule of thumb: daily generation ≈ PV capacity (kWp) × local peak sun hours × ~0.8 (system efficiency). So you can ballpark your own number once you know your PV size and local sunlight.

Worked example — 144kW PV (240 × 600W panels) in the Dominican Republic: The Dominican Republic averages roughly 1,600 kWh per kWp per year of usable PV yield. For a 144kW array, that works out to about:

In practice that means a sunny day's output can cover a large share of a warehouse running lighting, ventilation and some refrigeration through the day — and the surplus charges the 288kWh battery for use after sunset. Output runs higher in the dry, sunny months and lower during the cloudy/rainy season, so size the system to your real load rather than to a single peak day.

Sunnier, drier sites (e.g. parts of Jamaica or the southern Dominican Republic) can sit at the top of that range; cloudier or more shaded sites land lower. For a number tied to your exact location, we run it through PVWatts with your site conditions.

150kW solar storage system: price reference

Solar-plus-storage has no single "sticker price" — the final figure depends on panel count, battery capacity, on-grid/off-grid mode, mounting method, country, and local logistics and installation costs. The ranges below are 2026 market references for early budgeting; the actual quote depends on your specific design.

First, distinguish two kinds of pricing:

• Turnkey (installed) price: In mature markets such as the US/Europe, a 150kW solar + storage system runs roughly US$150,000–$250,000 turnkey, including local labor, permits, interconnection and soft costs.
• Factory-direct equipment price (FOB): As a factory-direct exporter, Sunchees supplies mainly the equipment (panels, inverter/PCS, battery, mounting, accessories), not destination-country installation or permitting. The equipment-direct price is therefore well below the turnkey price, with installation handled by you or a local team.

Sunchees is a solar system manufacturer based in Foshan, China, with its own factory, OEM/ODM support, and exports to 100+ countries. Common ways to buy a 150kW solar-plus-storage system:

Key procurement and delivery details:

How to choose: 150kW solar-plus-storage vs. the alternatives

A few comparisons buyers often weigh before ordering:

Factory-direct vs. local integrator vs. trading company

Solar-plus-storage vs. diesel generator

Many customers combine the two: solar by day, battery at night, with the diesel generator only as a last-resort backup — sharply cutting fuel use.

Choosing battery capacity

288kWh is a common configuration, but not the only option. Size the battery up or down based on required backup time and critical load (e.g. 200kWh, 260kWh, 315kWh). Bigger loads and longer backup call for a larger battery.

Choosing system power

If your load regularly exceeds 150kW, or you plan to expand, consider 200kW, 300kW or larger; for smaller loads, 100kW or below may be more cost-effective. Size it to your actual peak demand.

150kW solar storage for the Caribbean

Since 2008, Sunchees has exported solar systems across 200+ countries in the Caribbean and Latin America, factory-direct, with bilingual EN/ES support and CIF delivery to regional ports (such as Caucedo and Río Haina). For Caribbean commercial and industrial projects, a 150kW solar-plus-storage system is especially well suited to sites with high electricity costs, frequent outages and hurricane exposure — generate solar by day, store the surplus in the 288kWh battery, and keep critical loads running through outages.

Points that matter most for Caribbean projects:

• Hurricane resilience: Most islands sit in the hurricane corridor; coastal projects should use Cat-4-rated mounting and structural design.
• Outage backup: With aging grids and frequent blackouts, the 288kWh battery's backup value stands out — prioritize lighting, monitoring, cold storage, POS and control systems.
• Self-consumption + storage: Some countries cap commercial net metering / net billing at 25–100kW, and a 150kW system often exceeds the export cap — so the better strategy is self-consumption + storage rather than relying on grid export.
• Import tax exemptions: Many countries waive import duty and VAT on solar equipment (e.g. the Dominican Republic's Law 57-07 and Zonas Francas), significantly lowering landed cost.
• Voltage standards: Jamaica, the Dominican Republic, the Bahamas and Puerto Rico are mostly 120/240V split-phase; Barbados is 230V single-phase — choose the right inverter standard.
