SOLAR QUESTIONS.
STRAIGHT ANSWERS.

The cost of a turnkey solar power system in Uzbekistan starts at 5,000,000 UZS/kW for an on-grid system. This includes LONGi Hi-MO X10 panels, Deye inverter, mounting structures, and professional installation. Hybrid systems with battery storage start at 7,000,000 UZS/kW. The exact price depends on system size, roof type, and your consumption profile. Every DETOS proposal includes a full equipment breakdown with production estimates.

The average payback period for an on-grid solar system in Uzbekistan is 4–7 years. This is calculated using the current residential tariff of 1,000 UZS/kWh, solar irradiation of 4.0–5.2 peak sun hours (depending on region), and an assumed 5% annual tariff increase. With the feed-in tariff of 1,000 UZS/kWh for excess energy exported to the grid (Law No. 939, August 2024), payback accelerates. Use our calculator for a personalised estimate based on your actual consumption.

Direct purchase subsidies for solar panels are not yet available in Uzbekistan. However, several incentives exist: property tax exemption for solar installations (confirmed August 2024), feed-in tariff of 1,000 UZS/kWh for exported energy, and accelerated depreciation for businesses. DETOS provides full consultation on all available tax benefits and incentive programmes.

Typical timelines: Design and approvals — 2–4 weeks. Installation: residential (5–10 kW) — 2–3 days, commercial (30–100 kW) — 1–3 weeks, industrial (100+ kW) — 3–8 weeks. Full cycle from site assessment to connection: 4–8 weeks. DETOS provides a detailed project schedule at the proposal stage.

Most roof types are suitable: flat, pitched, metal tile, slate, corrugated sheet. Optimal orientation is south-facing with a tilt angle of 25–35° for Uzbekistan. East-west configurations also work with ~85% efficiency. If the roof is unsuitable, ground-mounted systems are available. DETOS conducts a free site survey to assess your roof and provide options.

Yes, with the property owner’s consent. A popular solution for businesses in rented premises: the solar system reduces operational electricity costs. Equipment can be dismantled when the lease ends. DETOS advises on the legal aspects and helps coordinate installation approval with the landlord.

LONGi panels: 30-year linear power warranty (guaranteed 87.4% output at year 30). Deye inverters: 5–10 years depending on model. Dyness lithium batteries: 10 years or 6,000+ cycles. Mounting structures: 25 years against corrosion and structural failure. DETOS installation work: 2 years. All warranties are manufacturer-backed with local support through DETOS.

Minimal maintenance required. Panels are self-cleaning during rain. We recommend a visual inspection every 6 months and dust cleaning during dry season (May–October). The inverter requires no user maintenance. DETOS provides 24/7 remote monitoring — we detect performance issues before you notice them. Estimated annual maintenance cost: near zero.

Yes, they work year-round. Winter output drops by 30–50% due to shorter days and lower sun angle, but production doesn’t stop. Panels are actually more efficient in cold weather (lower resistance). Cloudy day output: 10–25% of rated capacity. The annual energy estimate in our calculator accounts for seasonal variation month-by-month using real solar irradiation data from the Global Solar Atlas.

Panels: 30+ years (LONGi guarantees 87.4% output at year 30). Inverter: 10–15 years (one mid-life replacement factored into our payback calculation). Mounting structures: 25+ years. Dyness batteries: 10–15 years (6,000+ cycles). Total system design life: 30 years. After 30 years, panels still produce ~80% of their original output — they don’t suddenly stop working.

System size is matched to your consumption. Average home (500–800 kWh/month) → 5–8 kW (~12–13 panels). Small business (1,000–3,000 kWh/month) → 10–20 kW. Commercial facility → 30–100+ kW.

It depends on system type. On-grid: no batteries needed — excess energy is sold to the grid at the feed-in tariff. This is the lowest-cost option. Hybrid: batteries provide backup during outages. Recommended for businesses where downtime costs money. Off-grid: batteries are mandatory — the system is your only power source. DETOS installs Dyness LiFePO4 batteries, scalable from 5 kWh to 100+ kWh.

On-grid is more economical where grid access is stable: lower upfront cost (no batteries), payback in 4–7 years. Off-grid costs 40–60% more but is essential where there is no grid connection. Hybrid is the middle ground: backup during outages at moderate extra cost. 80% of DETOS clients choose on-grid. The right choice depends on your location, grid reliability, and budget.

The feed-in tariff was introduced by Law No. 939 (August 2024) and took effect with amendments to the Electric Power Industry Law. You sell excess solar energy to the grid at 1,000 UZS/kWh. Requirements: bidirectional meter, grid connection agreement with the regional power operator, and certified equipment. The process takes 3–5 weeks. DETOS handles all documentation and meter installation.

Five reasons. 1) ETL Certificate ML.2001 — DETOS is the only solar company in Uzbekistan with its own accredited electrotechnical laboratory. 2) 50+ completed installations across Uzbekistan. 3) Direct manufacturer contracts with LONGi, Deye, Dyness — no intermediaries, no counterfeits, competitive pricing. 4) Full-cycle service: from design and permits through to 24/7 post-installation support. 5) Free site survey and detailed proposal — no obligation, no pressure.

ETL (Electrical Technical Laboratory) is a state license issued by Uzbekistan’s Technical Regulation Agency. Certificate ML.2001 confirms DETOS’s accredited right to measure insulation resistance, verify grounding, test contact connections, and test transformer substations up to 10 kV.
