General

Is solar power really worth it for homes in Iraq?
Yes. Iraq is one of the sunniest countries in the region, with roughly 5.8–6.2 peak sun hours a day on average across most governorates. With long summer grid outages and expensive neighbourhood generator subscriptions, a well-sized system can cover a large share of your daily needs and cut your reliance on the generator. Results depend on your appliances, roof space and how many outage hours you want to cover, so start with our solar calculator for a first estimate.
My generator subscription is 10 amps. How much is that in kilowatts?
On Iraq's 220–230 V supply, each amp is roughly 220 W of load running at the same moment. So a 5 A subscription is about 1.1 kW and 10 A is about 2.2 kW. The subscription caps power (how many appliances run together), not energy. For comparison, a 6 kW inverter can carry loads equal to about 27 A at once, while the battery capacity decides how many hours those loads can run at night.
Is there a loan or financing for buying a solar system?
The Central Bank of Iraq runs a solar financing initiative with loans typically between 7 and 30 million IQD, repaid over 7 years. They are offered through participating banks and platforms such as tamwil.iq and the government Ur portal. Loan terms, interest rates and approved installers are set by the banks and the authorities and may change, so check with the bank before applying. We're happy to give you a detailed quotation for your chosen system to support your application.

Systems & sizing

What's the difference between a hybrid and an off-grid system?
A hybrid inverter manages panels, batteries and the grid or generator at the same time: it puts solar first and tops up from the grid, which suits larger homes with air conditioners. An off-grid inverter is designed for standalone operation and is usually more affordable. It can also take grid or generator power to charge the battery and feed your loads, but it doesn't blend the sources as flexibly. Since selling surplus power back to the grid isn't available to Iraqi households yet, both are normally set up with zero export.
How do I know what size system my home needs?
Size depends on four things: how much energy you use per day (kWh), the largest load running at one time (kW), how many outage hours you want to cover, and your governorate's peak sun hours. As a rough guide, a 3–4 kW system with 5–10 kWh of battery covers essentials plus a small daytime AC, a 6 kW system with around 16 kWh suits many family homes, and large homes may need 10 kW or more. Enter your appliances in our solar calculator for a recommendation based on your numbers, then review it with our team.
Can a solar system run air conditioners in summer?
Yes, as long as the system is designed for it. Inverter-type ACs are the best choice: a 1.5-ton inverter AC draws about 1.3 kW on average, while a similar standard AC draws about 1.8 kW with a start-up surge of up to three times that. Daytime cooling relies mainly on the panels; night-time cooling needs enough battery. Running one 1.5-ton inverter AC for eight hours at night uses roughly 10 kWh.
Can I sell surplus electricity back to the national grid?
Not at the moment. Federal Iraq has no net-metering scheme for households yet, so home systems are normally configured with zero export. Surplus solar is used to charge batteries or to run daytime loads such as the water pump, water heater and washing machine. If new regulations are introduced, many hybrid inverters can be configured to work with them.

Solar panels

Which panels should I choose: bifacial, N-type or back-contact?
Every panel we sell is N-type monocrystalline, which is more efficient and degrades more slowly than older P-type panels. Bifacial panels such as the Jinko Tiger Neo and Philadelphia Nexus also capture reflected light from the back, adding 5–25% according to the manufacturers when mounted high above a light-coloured surface. Back-contact panels such as the LONGi Hi-MO X10 reach up to 24.8% efficiency, giving you more power from the same area, which makes them ideal when roof space is limited.
Do extreme heat and dust affect panel output?
Yes. Every panel produces less as its cells get hotter, which is why the temperature coefficient matters; the Philadelphia Nexus, for example, loses only about 0.29% per °C. Leaving an air gap under the panels helps keep them cooler. Dust can cut output noticeably, especially after dust storms, so regular cleaning is an essential part of looking after a system in Iraq.
How and how often should I clean my solar panels?
Use plain water and a soft brush or long-handled mop, and clean early in the morning or after sunset when the panels are cool. Never spray cold water on hot glass. Avoid harsh detergents, abrasive tools and high-pressure jets. In dusty months, cleaning every two to four weeks and after every dust storm is usually enough. Stay safe on the roof and don't handle the cables or connectors.

Inverters

Do I need a single-phase or a three-phase inverter?
Most Iraqi homes run on a single-phase 220–230 V supply, which is what our Deye SG05LP1 hybrid and Deye OG03 off-grid inverters are built for. Three-phase is used in larger buildings, workshops and factories with three-phase motors. If you're not sure what supply you have, send us a photo of your distribution board and we'll help you work it out.
Can the inverter work with my neighbourhood generator line?
Yes. Hybrid and off-grid inverters accept an input from the grid or a generator to feed your loads and charge the battery when needed; the Deye OG03, for example, has a 35 A grid/generator input. One important tip: set the inverter's AC charging current so it stays within your subscribed amps, otherwise the generator breaker may trip while the battery charges.
Can I expand my system later?
Usually yes, within the limits of the components you choose. You can add batteries in parallel (Deye SE-F batteries up to 32 units, Dyness PowerBrick SC up to 50), run up to 16 Deye inverters in parallel, and add panels within the inverter's PV voltage and current limits. That's why we recommend planning for growth from day one, for example by choosing an inverter slightly larger than you need today.

Batteries

Why choose LiFePO4 lithium instead of gel or lead-acid batteries?
LiFePO4 batteries handle thousands of charge cycles: Deye SE-F batteries are rated for 6,000+ cycles and the Dyness PowerBrick SC for 8,000+, compared with a few hundred to around a thousand for typical lead-acid batteries. They also allow much deeper discharge, need no maintenance, use a stable and safe chemistry and talk to the inverter through their battery management system (BMS). They cost more up front, but far less per cycle over their life.
How many years does a lithium battery last?
Manufacturers rate battery life in cycles until 70% of capacity remains under specific test conditions: 6,000+ cycles for Deye SE-F batteries and 8,000+ for the Dyness PowerBrick SC. At one cycle a day that's a long theoretical life, but real-world life depends on temperature, depth of discharge and charge rates. The warranty follows each manufacturer's terms, such as a number of years or total energy throughput, and is listed on every battery's page.
Where should the battery go, and does summer heat affect it?
The home batteries we sell are designed for indoor installation (IP20 or IP21), so place them somewhere covered and well ventilated, away from direct sun, water and heat sources. The allowed charging range is usually 0–55 °C, and constant high heat shortens any battery's life. Avoid putting it on the roof or inside a closed metal box in summer.

Ordering & delivery

How do I order and pay? Are the listed prices final?
Add products to your cart and check out on the website, or send your order straight to us on WhatsApp. Our team then contacts you to confirm availability, the final price and delivery details. You can pay cash on delivery, by bank transfer or with ZainCash, as agreed when the order is confirmed. Prices are listed in Iraqi dinars and can change with the exchange rate and supplier prices; the price we confirm with your order is the one that applies.
Do you offer delivery and installation?
Yes. We arrange delivery to your governorate and can arrange installation by qualified technicians. Delivery and installation costs and timing depend on your location, system size and roof, so we confirm them with you for each order. You can also collect the order yourself if that suits you better.

Warranty

What warranty do the products come with?
Our products carry their manufacturers' warranties, under each manufacturer's terms. For example, panels come with a 12–15-year product warranty and a 30-year linear power warranty, Deye inverters with 5 years that can be longer depending on the installation country, and batteries with 5–10 years or a set energy throughput according to the manufacturer's warranty letter. Each product page lists its warranty, and we help you follow up any claim with the manufacturer or its agent.
What should I do if something goes wrong with my system?
Contact us with your order or invoice number, the device's serial number, photos or a short video, and any error code shown on the inverter screen or app. We'll help with a first diagnosis and follow up the warranty claim under the manufacturer's terms. Note that warranties usually don't cover damage caused by incorrect installation, misuse, breakage or water ingress.
