EA300 Pilot reported having an electrical failure after takeoff and returned to departure airport.

Narrative

On Date at approximately XA:00; while PIC on a solo flight in my Extra 300L; I had a rolling electrical failure (first on one device; then sequentially lost use of other devices) about a minute; or so after take-off from ZZZ Runway XX with a left crosswind turnout to the Southwest. Conditions were VMC; sky clear; 10+ miles of visibility. Here is what happened: Shortly after take-off; I noticed that I lost the ADS-B (Automatic Dependent Surveillance Broadcast) traffic feature on my G430; so I recycled it; but when the G430; including Com. 1; didn't come back on after 30-60 seconds; I knew something was amiss. Initially; after the Com. 1 failure; my Com. 2 was lit up; but by the time I went to use it to call the Tower; Com. 2 did not work; I then noticed the Communications panel was dead and then the LED lights on my Com. 2 went out so; I knew it too was dead. It was at this point I realized I had lost my radios and all other electricals as my tachometer too was dead. I ran a quick check of all circuit breakers; all the while maintaining control of the plane and looking for other traffic. All breakers were in; so the only prudent choice for mine and others safety; was to head back to ZZZ (NORDO). Upon reaching midfield to the West of the Tower; at about 1000 ft. AGL; I then circled around in this area to the West of the Tower about 1000 ft. or so away from it and wagged my wings over and over for what seemed like 2-3 minutes or so. To be safe; I did not want to overfly the field because the area to the East of the field there is an aerobatic box that is quite often active and there are helicopters and military aircraft at the field as well as a Company facility. I figured the Tower would see and hear me where I was and could also see me on radar. After some time; I saw no light gun from the Tower at all; so I figured that maybe it was broken. I then went southbound in the downwind towards left pattern for Runway XX and before turning base; I saw that a Aircraft X or similar aircraft was on a take-off roll; so I went back to the area West of the Tower and did some more circling and wing wagging. I was concerned; but not panicked; that this could develop into an emergency; if this electrical failure was the beginning of more going wrong with my plane; (maybe an engine failure; fire; etc.) if there was a short of some kind that might also take the magnetos off-line. So; I wanted to stay close to the field/Runways. Then being in the area to the West of the Tower; after I saw the Aircraft X take-off and away from the area and saw no planes on base; or approach; I figured it was most prudent to bring my plane in for a landing (as the AIM says with a com. failure; 'land as soon as practicable'). As I was already in the downwind for a left base; I kept close to the runway/did a moderately short approach; in case I had an engine failure. This was all the while I was pretty sure that the Tower must have seen me with all my extensive circling and wing wagging. As I was NORDO; I got off on [taxiway] A3 and then taxied back to the ramp. As soon as I exited the plane; I called the Control Tower to let them know I had a total electrical failure and the person I spoke to said given the conditions I did a good job. I gave them my name; tail number and phone number to file in their report to the FAA. They said the total electrical failure would explain why they didn't see me on ADS-B. I was surprised to find out that they didn't have radar at all to see planes with INOP ADS-B. Since the event this is what has been done. The aircraft was grounded and sent to maintenance shop to replace the battery; starter motor; alternator and to check all electrical systems. Return to service logbook sticker will show replaced battery; alternator; starter; etc. What I will do in the future: Carry a handheld battery operated radio and the control tower frequencies in for departure and arrival airports in my phone.
