Common Myths About Solar Energy and the Real Facts Businesses Should Know

Many businesses consider solar energy only after hearing conflicting opinions: some say that solar panels work only in hot weather, others expect a solar power plant to replace the grid completely, and some believe that PV modules lose efficiency too quickly. This article separates common myths from practical facts. It is useful for owners of warehouses, shops, production sites, offices, farms and service facilities that are comparing suppliers, project risks and the real technical logic of a solar power plant.

Why solar myths lead to wrong business decisions

A solar power plant should not be assessed by general impressions. The useful question is not simply whether there is enough sun, but how the facility consumes electricity during the day, where panels can be installed, whether shading exists, what the grid connection allows, and how the load may grow in the future. A system that works well for one warehouse may be unsuitable for another building with a different operating schedule.

According to data published by Qazaq Green with reference to the Ministry of Energy of the Republic of Kazakhstan, renewable energy facilities generated 7.58 billion kWh in 2024, equal to 6.43% of total national electricity production. Solar power plants generated about 1.89 billion kWh, while installed solar capacity reached 1,222.61 MW. These figures show that solar energy is already part of the energy mix, not just an experimental idea.

Before requesting a quotation, a business can check the supplier’s public profile and service direction through the company profile on Mytrade.kz. However, the final decision should always be based on facility data, not only on general market growth.

Myth 1: solar panels work only in hot weather

Fact: PV panels generate electricity from light, not from heat itself. High temperature is not automatically beneficial; in some conditions, it can reduce module performance. That is why system design must consider panel orientation, tilt angle, ventilation, cable losses, dust, seasonal changes and shading from nearby structures.

For a commercial facility, this changes the whole approach to planning. A shop, warehouse, workshop or agricultural site with strong daytime consumption may use solar generation more effectively than a facility where the main load appears at night. To compare available directions of work and equipment-related offers, it is useful to review the current seller offers before preparing a technical request.

Data worth collecting before the first calculation

• electricity bills for the last 12 months;
• daytime and nighttime load split;
• available roof or land area;
• photos of the roof, electrical room and possible shading zones;
• planned load growth, such as new machines, refrigeration, pumps, ventilation or charging equipment.

Myth 2: once solar is installed, the grid is no longer needed

Fact: a solar power plant does not always have to replace the grid. In many business projects, the main purpose is to cover part of daytime consumption, reduce purchased electricity from the grid and make energy costs more predictable. Full autonomy is a separate engineering task that usually requires batteries, backup sources and a different control scheme.

The International Energy Agency expects solar PV to remain one of the major drivers of renewable power capacity growth. Still, global growth does not mean that every facility needs the same configuration. For a business, the key question is whether a grid-tied, hybrid or autonomous solution matches the actual operating mode of the site. TОО "Helio Solar" works in solar energy, including supply, design, installation and maintenance of solar power plants, so the request should be built around the object’s load profile, not around a random number of panels.

Visual materials can also help a client understand how solar solutions look in practice. Examples and short videos are available in the company Reels videos.

Myth 3: solar panels degrade too quickly

Fact: PV modules do degrade, but degradation is not the same as rapid failure. An analytical review by NREL collected nearly 2,000 degradation rates from modules and systems and reported a median value of about 0.5% per year. For a business, this means that the system should be evaluated as a long-term engineering asset, not as a short-season purchase.

The larger practical risk is often not the module itself, but poor system planning: incorrectly selected inverter capacity, underestimated cable losses, weak protection devices, insufficient monitoring or lack of maintenance access. If the system is difficult to inspect and clean, performance losses may appear faster than expected. This is why the technical scope should include not only panels, but also inverter selection, protection, cable routing, mounting structure and monitoring.

Myth 4: solar energy is mainly for private houses

Fact: many commercial facilities have a more stable daytime load than private homes. Retail outlets use lighting, refrigeration, cash register areas and ventilation during business hours. Production sites operate machinery, compressors, pumps and storage equipment. Agricultural facilities may have pumping, cooling or ventilation loads that coincide with daylight hours.

The strongest business case appears when daytime generation overlaps with daytime consumption. But even in this case, the facility must be checked carefully: roof load capacity, free area, shading, seasonal consumption, electrical protection and future expansion plans all matter.

Myth 5: buying panels is enough

Fact: panels are only one part of a solar power plant. A complete system includes inverters, protection devices, cables, mounting structures, distribution panels, monitoring, project calculations and installation work. A mistake in one component can reduce total generation, increase downtime or create additional expenses after launch.

For a commercial site, at least five technical blocks should be checked: the planned capacity compared with daytime load, temperature and cable losses, roof or land suitability, inverter and protection equipment, and future maintenance access. TОО "Helio Solar" works with solar power plants for private, commercial and industrial facilities, so a practical request should include the type of building, electricity consumption, available area and operating schedule. Wider business comparisons can be made through the Mytrade.kz marketplace.

When facts replace assumptions

Solar myths are risky because they simplify an engineering decision. A solar power plant depends on sunlight, but it is calculated through load profile, seasonality, equipment choice and the physical conditions of the object. Maintenance is necessary, but that does not mean constant equipment replacement. Solar can reduce grid consumption, but the result depends on whether the configuration fits the facility.

Before contacting TОО "Helio Solar", a business should prepare 12 months of electricity data, photos of the installation area, information about daytime equipment, available grid capacity and expected growth in consumption. This makes the discussion more specific and helps compare suppliers on technical substance rather than general promises.
