You can install this complete DIY 49 solar panel power set yourself and put it together entirely as you wish. 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 tailored specifically to your situation.
Step 1: Solar panels
Choose the 49 solar panels you want to use in your 49 solar panel power set. You can choose between 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 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, they start up early and shut down late. That way your yield is maximized. One panel more or less is usually 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 precise.
Solaredge is a popular inverter because of the way it handles shade, but it is relatively expensive. These inverters only work if every single 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 spare circuit. Do you have a three-phase connection? Then it is better to switch to a three-phase inverter sooner rather than later. Always connect your inverter to a spare circuit to avoid the risk of fire, 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 an elegant solution in which you only have to fit those particular panels with an optimizer. That saves a considerable amount in 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 display 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 that hook. We also ask whether you want to fit the panels portrait or landscape. Portrait means that the short side of generally 1000mm is positioned horizontally. In landscape you have the long side of generally 1650 mm horizontally. 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. Based on this we can calculate how many end clamps you need to install your complete solar panel set yourself.
Step 8: Cabling
A complete DIY 49 solar panel power set cannot do without solar cable. This runs from the inverter to the nearest panel and back from the furthest panel 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. You therefore do not need any extra metres for that. If you tell us how many metres you need to connect your furthest panel, we will supply that length twice, or four times if you have chosen an inverter that can handle multiple strings. We crimp the MC4 connectors on for you 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 using an earthing cable. If you order an earthing cable from us, we crimp the mounting eyelets 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 5-core YMVK cable.
Step 9: Check your DIY 49 solar panel power set yourself and add it to your basket
Once you have followed all the steps, you can check your choices and place the complete DIY 49 solar panel power set in your basket yourself. Do you have a special layout or other wishes? Then state this in the comments section when ordering. That way 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 start mounting them. Not sure how to proceed? Feel free to get in touch! Our remote advice does not stop after delivery.
