35 solar panel set

You can install this complete DIY 35 solar panel power set yourself and put it together entirely to your own wishes. A complete set consists of solar panels, an inverter, complete mounting material and cabling. Once you have gone through all the steps we know exactly what you need and you will see a price that is tailored specifically to your situation.

Step 1: Solar panels

Choose the 54 solar panels you want to use in your 35 solar panel power set. You can choose from poly (dark blue with an aluminium frame) or mono (black) panels. The quality is the same, it is purely a matter of colour. For the exact specifications you can click on the datasheet, or view the panel in the webshop.

Step 2: Inverter

Choose the inverter you want. They are available in various price ranges.

Growatt is a Chinese inverter with a very good price-quality ratio. These inverters are very flexible, start up early and shut down late. That maximises your yield. One panel more or less is often no problem at all for these inverters. Growatt is also known for its quiet inverters thanks to natural cooling.

SMA inverters are produced in Germany and are somewhat more expensive, but a good deal less forgiving. With SMA the connected peak wattage is very critical.

Solaredge is a popular inverter because of the way it deals with shade, but it is relatively expensive. These inverters only work if every panel is fitted with a SolarEdge optimizer.

It is important to check what kind of grid connection you have. Do you have a single-phase connection? Then you can often fit a larger single-phase inverter on your dedicated circuit. Do you have a three-phase connection? Then it is better to switch to a three-phase inverter sooner. You always connect your inverter to a dedicated circuit to prevent fire hazards, as laid down in NEN 1010:2015.

Step 3 + 4: Optimizers / Monitoring

Do you have shade on your roof? Then it may well pay off to optimize the panels that catch that shade. Tigo Energy has a neat solution where you only have to fit an optimizer to those panels. That saves considerably on costs. You can easily add these optimizers to your set afterwards.

It is incredibly addictive to monitor how your DIY set is performing. You can of course do this on the screen of the inverter, but how fantastic is it to keep an eye on the graphs 24 hours a day on your phone or computer!

Step 5 + 6 + 7: Roof type / Mounting method / Rows

To determine which mounting material is suitable for your roof, we ask you to tell us your roof type. You can then indicate what kind of hook / clip / screw / support or mounting foot you need. The price you see is not for 1 hook, but for the complete mounting material using this hook. We also ask whether you want to place the panels in portrait or landscape. Portrait means that the short side, generally 1000mm, is horizontal. In landscape you have the long side, generally 1650 mm, horizontal. Landscape mounting is always slightly more expensive because you then need more rails. We always supply the mounting rails horizontally. Finally we ask you to indicate the number of rows you want. By this we mean the number of horizontal rows. On that basis we can calculate how many end pieces you need to install your complete solar panel set yourself.

Step 8: Cabling

A complete DIY 35 solar panel power set cannot do without solar cable. This runs from the inverter to the nearest panel and from the furthest panel back to the inverter. Behind the panels there are short cables, so that panels lying next to each other can always be connected to one another. So you do not need any extra metres for that. If you tell us how many metres you need to connect your furthest panel, we supply that length twice, or four times if you have chosen an inverter that can handle several strings. We crimp the MC4 connectors on in advance, so you do not have to buy a special MC-4 crimping tool. Would you rather crimp the connectors on yourself? No problem, just let us know.

Under the new NEN 1010:2015 it is mandatory to earth the panels. You do this by connecting the nearest panel frame to the inverter with an earthing cable. If you order an earthing cable from us, we crimp the ring terminals on in advance. That again saves you buying a crimping tool. Finally, you can connect the inverter to the meter cupboard using YMVK cable. The 3-core cable is suitable for a single-phase inverter. Have you selected a three-phase inverter? Then choose the YMVK 5-core cable.

Step 9: Check your DIY 35 solar panel power set and add it to your basket

Once you have followed all the steps you can check your choices and place the complete DIY 35 solar panel power set in your basket yourself. If you have a special layout or other wishes, please state this in the comments section when ordering. Then we know what to pack. We usually aim for delivery on the next Saturday, but sometimes that is not possible. In that case you will usually have your panels at home a week later and can mount them. Not getting anywhere? Feel free to get in touch! Our remote advice does not stop after delivery.
