Solar Quotes in Antalya: How to Compare Them in 10 Line Items

You have three solar quotes in Antalya on the table, and all three show the same system size on the first line. Picking the lowest total looks tempting, but more often than not it means comparing apples with oranges. This guide unpacks the ten line items that make up a quote one by one, shows the “same kWp, different system” traps and gives you a comparison template ready to fill in. We are not talking prices here, because a sound comparison starts with what is inside the quote, not with the final figure.

Why solar quotes in Antalya can’t be judged on the total alone

An Antalya solar energy system is a package made up of panels, an inverter, a battery where included, the mounting structure, cabling, protection devices and the official paperwork. When the class of any one of these items changes, both the upfront investment and the system’s performance over the years change with it.

Two quotes may show the same capacity, for example, yet one includes a hybrid inverter and a battery while the other has only an on-grid inverter. One may specify mounting materials suited to a coastal environment while the other says nothing about it at all. With quotes for solar panels in Antalya, these differences only become visible once the line items are placed side by side.

Check the 10 line items of a quote one by one

The headings below also form the rows of the comparison template. For each one we summarise what the quote should state and what you should watch out for.

1. System size (kWp)

kWp is the total rated power of the panels under standard test conditions — the number of panels multiplied by the power of a single panel. Seventeen 605 W panels make 10.285 kWp. Ask for this multiplication to be written out clearly in the quote; a rounded “10 kWp” can hide the real number of panels. For correct sizing, see our article on how many kW of solar panels you need.

2. Panel brand, model and wattage

“Grade A panel” or “high-efficiency panel” is not a model name. The quote should state the manufacturer, the full model code, the wattage and the cell technology (for example TOPCon N-Type). With the model code you can find the datasheet and check efficiency, temperature coefficient and certifications yourself.

3. Inverter type and power

Whether the inverter is on-grid, hybrid or off-grid determines what the system can do: an on-grid inverter shuts down for safety reasons when the grid fails, whereas a hybrid inverter can keep running on the battery. The quote should also state whether it is single-phase or three-phase, its rated AC power and the number of MPPT inputs. An inverter that is undersized or needlessly oversized relative to the panel capacity affects both efficiency and cost. For more detail, read our guide to choosing a hybrid inverter.

4. Battery capacity and cycle count

If a battery is included, its chemistry (for example LiFePO4), nominal capacity (kWh), usable capacity and the number of cycles covered by the warranty should each be stated separately. The gap between nominal and usable kWh is set by the depth of discharge. Our article what is a LiFePO4 battery explains the differences between chemistries.

5. Mounting system

Mounting varies with the roof type: tile hooks, clamps for trapezoidal or sandwich panel roofs, or a ground-mount structure. The quote should state the type of material (aluminium, stainless fasteners and so on) and confirm that it suits your roof. On the Antalya coastline, salty air makes the choice of fastener material even more important. For the options, see our article on solar panel mounting systems.

6. Cabling and protection devices

Solar DC cable cross-section, MC4 connectors, DC and AC fuses, surge protection and earthing are often squeezed into a single line of the quote. Ask what that line actually contains; missing protection devices are usually noticed only when a fault or a lightning strike exposes the problem.

7. Design and application work

For net metering (mahsuplaşma) systems, the quote should state who will handle the application to the distribution company Akdeniz EDAŞ (AEDAŞ), the design drawings and the acceptance procedures. If this work is not included in the quote, it may turn up later as a separate item.

8. Warranty documents

Panel, inverter and battery warranties are provided by the manufacturer and vary by model. The quote should clearly state the warranty period for each product and confirm that the warranty documents will be handed over at delivery.

9. Delivery time

The number of working days within which the installation will be completed after signing should be stated in writing. For net metering systems, the official application process runs separately from the installation; the quote should not blur these two timelines together.

10. Maintenance and monitoring

Ask which app or monitoring device you will use to track the system’s output and what the periodic maintenance covers. With a system that has no monitoring, a fault is often noticed only when the electricity bill arrives.

“Same kWp, different system” traps

The most common situation when comparing Antalya solar energy quotes is that different systems sit behind the same capacity figure. These are the main traps to watch out for:

• Rounded capacity: a quote that says “10 kWp” may contain fewer panels. Always do the panel count × panel power calculation yourself.
• Type difference: two systems with the same kWp, one with an on-grid and one with a hybrid inverter, behave completely differently during a power cut.
• Battery capacity: nominal kWh and usable kWh are not the same thing. The number of cycles covered by the warranty should be compared as well.
• Panel technology: two panels with the same wattage can perform differently in an Antalya summer because of differences in cell type and temperature coefficient.
• Mounting materials: in coastal areas, a visible difference develops over the years between corrosion-resistant materials and ordinary fasteners.
• Work outside the scope: if the application, the design work or the monitoring device has been left out of the quote, a total that looks lower may not be lower in the end.

The way to protect yourself from these traps is to map every quote onto the same rows. The template below was prepared for exactly that purpose.

Print the table and fill in the column for each quote. Every cell left empty is a question you need to put to the solar installer.

Verify the yield estimate in solar quotes in Antalya

Most quotes also include an annual yield estimate. There is a practical way to test that figure: according to PVGIS 5.3 data, a 1 kWp system in central Antalya facing south at the optimum tilt of 33°, with 14% system losses assumed, produces a theoretical 1,656 kWh per year. Shading, soiling and deviation from due south reduce this value.

On that basis, the theoretical annual yield of a 10 kWp system is around 16,560 kWh. If a quote shows noticeably higher production for the same capacity, ask for the basis of the calculation. For a quick estimate for your own roof, you can use the calculator below.

The value the calculator gives is also theoretical; the real tilt, orientation and shading of your roof only become clear during the site survey. Even so, it lets you see whether the estimates in the quotes fall within a reasonable range.

Final checks before signing the contract

Once you have filled in the comparison table, make sure the quote you choose is carried over into the contract in full. The product models in the quote should appear in exactly the same form in the contract; if there is an “or equivalent” clause, it should state under which conditions and with which model a product may be substituted.

Linking the payment schedule to the stages of the work, stating the delivery time in working days and listing the documents to be handed over are clauses that protect both sides.
