Hotel Solar Energy in Antalya: Investment Guide for Tourism Facilities

Hotel solar energy in Antalya is a sensible option for a facility whose air-conditioning, kitchen and pool loads peak in summer, because the months of highest production coincide with the months of highest consumption. This overlap does not make the investment profitable by itself. Roof area, contract power, night load and regulatory limits decide the outcome. In this article we list the points a facility manager should know before a feasibility study.

How summer peak overlaps with production in hotel solar energy

According to PVGIS data, 1 kWp of installed power in central Antalya produces about 168 kWh in July, 167 kWh in August and 159 kWh in June. In December this value is 99 kWh. That is, summer output is about 1.7 times winter output (calculation). The consumption curve of a hotel whose season is busy between April and October largely resembles this shape.

According to the General Directorate of Meteorology (MGM), average daily sunshine duration in Antalya in July is 11.7 hours. The average maximum temperature reaches 34.2 °C. At this temperature the air-conditioning load rises, while panels also lose some efficiency because of heat. The 14% system loss that PVGIS uses includes this effect.

Hotel load profile: day, evening and night

Solar energy produces only in the daytime. You therefore first need to draw up the facility's 24-hour load profile. In general, these loads are spread across the daytime hours:

• Air conditioning of lobbies, corridors and meeting areas
• Laundry, kitchen and cold-room equipment
• Pool circulation and filter pumps
• Ventilation and booster pump systems

Evening and night loads stay high because of room air conditioners, lighting and restaurant service. A battery is needed to meet this part directly from solar production. We touch on the battery's role and the storage rule below. Meter data (15-minute or hourly consumption) is the first input of the feasibility study. With a year of data you can see the summer-winter difference and the weekday-weekend difference.

An electricity-focused approach, not hot water

This article covers only photovoltaic systems that generate electricity. Solar collectors for hot-water needs in hotels are a separate subject and require a different engineering calculation. The production of a photovoltaic system is assessed against consumption on the facility's electricity bill. If you have electrically powered hot-water equipment, it naturally appears in the load profile, but the basis of the solution is still the kWh balance.

Roof, car park and open-space options

Three types of surface stand out in tourism facilities in Antalya: hotel block roofs, technical-room roofs and open car parks. On roofs, assessing the supporting structure is essential. The load-bearing capacity of the roof needs to be assessed by a civil engineer. The distribution company and the municipality may ask for a structural suitability certificate.

Car-park canopies (carports) can be an alternative for facilities with insufficient roof. They provide shade for vehicles and also create a generation area. For details, see our article on carport solar energy systems. If your facility is in a heritage site or protected zone, additional permits may be needed. Clarify the facility's location at the very start of the feasibility study.

First steps for a feasibility study

A hotel solar energy project should be built on data, not on estimates. Collecting the following information before the survey speeds up the process:

1. Electricity bills for the last 12 months and, if possible, an hourly or 15-minute consumption profile
2. Subscription type, unique code and contract power information
3. Roof plans, roof covering type and any structural reports
4. The facility's title deed or right-of-use document
5. Structures casting shadows, trees and roof equipment such as chimneys and vents

When this data is combined with an on-site survey, it becomes clear which part of the roof will be used and what power the system can carry. Project design and application steps then begin.

Capacity and regulatory limits

Under the rules in force as of October 2026, the following points are decisive for non-residential facilities such as hotels. Because regulations change often, we recommend confirming the current text before applying.

• Consumers other than municipalities, industrial facilities and agricultural irrigation are limited to their contract power. The size of a system installed on a hotel roof therefore cannot exceed the facility's contract power.
• For installations that received a connection approval letter (çağrı mektubu) after 12 May 2019, production in a calendar year cannot exceed twice the associated consumption.
• From 1 May 2026, net metering (mahsuplaşma) for these non-residential installations is hourly. Producing in the daytime and consuming in the same hour is worth more than relying on surplus.
• Main equipment such as panels, inverters and batteries must have been manufactured within the last five years.

An installation run without acceptance has its connection cut and its owner cannot apply for three years. An approach of "let's run it first and complete the paperwork later" is therefore risky even in the tourism season. For the application steps, see our article on the rooftop solar application.

Why self-consumption is critical under hourly net metering

In non-residential installations, production and consumption are netted separately for every hour. Surplus is valued at the single-rate active energy unit price of the relevant tariff. This amount is lower than the total unit charge on the bill, because the bill amount also includes the distribution charge and taxes. Sizing a hotel solar energy system to the facility's daytime consumption, rather than to selling surplus production, is therefore often the sounder approach. This interpretation rests on the payment principles in Decision 14531. The net metering rules are explained in a separate article.

Battery: an option that enlarges the investment but covers the evening load

The owner of a licence-exempt installation can install a storage unit up to the electrical power of the generation plant. No payment is made for energy fed from the battery to the grid. The battery is therefore not a sales tool but a way to consume the daytime surplus in your own facility in the evening. In a hotel solar energy system, a battery is mostly considered to back up critical loads (lighting, reception, cold room) or to cut the evening peak. Battery warranty varies by brand and model. For example, in one manufacturer's low-voltage battery series the product warranty is 60 months. Be sure to ask for this period in writing in the quote. For the technical background, see our article on LiFePO4 batteries.

A sample calculation: a 100 kWp rooftop system

The table below shows a hypothetical calculation. The figures are based on PVGIS's value for a south-facing system at optimum tilt in central Antalya. On a real roof, the result may come out lower because of tilt, orientation and shading. This is not a price or savings promise.

How much of this production will be consumed in the facility depends on the load profile. For the payback calculation you can also use the method in our article on the payback period of solar energy.

Implementation and operating notes for a tourism facility

If the facility is closed or has low occupancy outside the season, production appears as surplus on the meter side. In winter months production is low anyway, but the facility's consumption may also fall. How production will be treated in this period, that is, how much will be consumed in the facility and how much counted as surplus, should be planned from the start. In tourism facilities the system size is therefore set by looking at the balance of summer and winter load, not just the peak of the season. The installation timetable matters too. Installing before the season, in the November-March period when the hotel is quiet, protects guest comfort. A monitoring system lets you see how much each block produces. Also, for fire safety, panels must be mounted on a fire-resistant surface with a ventilation gap left behind them. Installation contrary to the installation manual can void the warranty.

Among the references on Solar Nexo's website are a 450 kW commercial building roof, an 860 kW industrial roof and a 970 kW factory roof. These are commercial and industrial references, not hotels. However, the survey, design and application process for large roofs follows similar steps. For factory and commercial roof experience, you can review our references.

Conclusion

A hotel solar energy investment has a strong basis in Antalya thanks to the overlap of summer load and production. However, the right size must be assessed together with contract power, hourly net metering and night load. Load data comes first, then roof and structure, then regulation and application steps.
